Electrochemical CO_(2) reduction reaction(CO_(2) RR),powered by renewable energy sources,provides an appealing approach to convert emitted CO_(2) to value-added chemicals and fuels and achieve a carbon-neutral cycle.Among various carbon-based products,formic acid(HCOOH) has been considered as a promising liquid hydrogen storage material due to its high energy density and hydrogen content.However,so far,the reported HCOOH-selective catalysts(e.g.,Bi,Sn,In,Pb and Pd) have failed in either activity(<500 mA cm^(-2)) or stability(<20 h),which significantly inhibits the industrialized feasibility of CO_(2) RR.In contrast,Cu takes the advantages of excellent activity and low cost,making it more commercially viable.To date,one of the most challenging issues of Cu-based catalysts lies in unsatisfactory selectivity,that is,tending to produce mixed products rather than specific one,due to the complicated reaction paths involved.Very recently,Zheng et al.have developed a single-atom alloy(SAAs) strategy for the exclusive CO_(2)-to-formate conversion over Cu-based catalysts.The as-prepared Pb single-atom alloyed Cu catalyst(Pb_(1)Cu)(Fig.la) exhibited near unity selectivity towards HCOOH and impressive stability,providing the prospect of industrial production of HCOOH from CO_(2).

The increase of atmospheric CO_(2)concentration has caused many environmental issues.Electrochemi-cal CO_(2)reduction reaction(CO_(2)RR)has been considered as a promising strategy to mitigate these chal-lenges.The electrocatalysts with a low overpotential,high Faradaic efficiency,and excellent selectivity are of great significance for the CO_(2)RR.Carbon-based materials including metal-free carbon catalysts and metal-based carbon catalysts have shown great potential in the CO_(2)RR,owing to the tailorable porous structures,abundant natural resources,resistance to acids and bases,high-temperature stability,and en-vironmental friendliness.In this review,various carbon materials including graphene,carbon nanotubes,quantum dots,porous carbon,and MOF-derived catalysts,etc.,for the CO_(2)RR have been summarized.Particularly,recent progress in terms of the mechanism and pathway of CO_(2)conversion has been com-prehensively reviewed.Finally,the opportunities and challenges of carbon-based electrocatalysts for the CO_(2)RR are proposed.

The carbon cycle is an important process that regulates Earth's evolution.We compare two typical periods,in the Paleoproterozoic and Neoproterozoic,in which many geological events occurred.It remains an open question when modern plate tectonics started on Earth and how it has influenced the carbon cycle through time.In the Paleoproterozoic,intense weathering in a highly CO_(2)and CH_(4)rich atmosphere caused more nutritional elements to be carried into the ocean.Terrestrial input boosted high biological productivity,deposition of sediments and the formation of an altered oceanic crust,which may have promoted an increase in the oxygen content.Sediment lubrication and a decrease in mantle potential temperature made cold and deep subduction possible,which carried more carbon into the deep mantle.Carbon can be stored in the mantle as diamond and carbonated mantle rocks,being released by arc and mid-ocean ridge outgassing at widely different times.From the Paleoproterozoic through the Neoproterozoic to the Phanerozoic,the carbon cycle has promoted the evolution of a habitable Earth.

Multiple myeloma(MM)is a hematologic malignancy in which plasma cells proliferate in the bone marrow,leading to osteolytic bone destruction.Bone involvement is present in up to 90%of patients with MM and is associated with pain and skeletal-related complications,such as pathologic vertebral compression fractures(VCFs).^([1])MM-associated VCFs cause spinal instability,back pain,spinal kyphosis,neurologic dysfunction,and subsequent respiratory complications,which markedly decrease the quality of life of affected patients.

Electrocatalytic CO_(2) reduction reaction(CO_(2) RR) can store and transform the intermittent renewable energy in the form of chemical energy for industrial production of chemicals and fuels,which can dramatically reduce CO_(2) emission and contribute to carbon-neutral cycle. E cient electrocatalytic reduction of chemically inert CO_(2) is challenging from thermodynamic and kinetic points of view. Therefore,low-cost,highly e cient,and readily available electrocatalysts have been the focus for promoting the conversion of CO_(2). Very recently,interface engineering has been considered as a highly e ective strategy to modulate the electrocatalytic performance through electronic and/or structural modulation,regulations of electron/proton/mass/intermediates,and the control of local reactant concentration,thereby achieving desirable reaction pathway,inhibiting competing hydrogen generation,breaking binding-energy scaling relations of intermediates,and promoting CO_(2) mass transfer. In this review,we aim to provide a comprehensive overview of current developments in interface engineering for CO_(2) RR from both a theoretical and experimental stand-point,involving interfaces between metal and metal,metal and metal oxide,metal and nonmetal,metal oxide and metal oxide,organic molecules and inorganic materials,electrode and electrolyte,molecular catalysts and electrode,etc. Finally,the opportunities and challenges of interface engineering for CO_(2) RR are proposed.

Rational design and synthesis of multimetallic nanostructures(NSs)are fundamentally important for electrochemical CO_(2)reduction reaction(CO_(2)RR).Herein,a multi-step seed-mediated growth method is applied to synthesize asymmetric AuAgCu heterostructures using Au nanobipyramids as nucleation seeds,in which their composition and structures are well controlled.We find that the selectivity of C_(2)products for CO_(2)RR could be effectively regulated by tandem catalysis and electronic effect over trimetallic AuAgCu heterostructures.Particularly,the Faraday efficiency toward ethanol could reach up to 37.5%at a potential of−0.8 V versus reversible hydrogen electrode over asymmetric Au1Ag1Cu5 heterostructures with segregated domains of three constituent metals.This work provides an efficient strategy for the synthesis of multicomponent architectures to boost their promising application in CO_(2)RR.

This is an expert consensus on the evaluation and treatment of thoracolumbar spinal injury, estab- lished from February 2009 to July 2010. The expert consensus consists mainly of six parts with a total of 54 recommendations including the overview （one item）; pre-hospital care （one item）; evaluation and diagnosis （13 items）; treatment （23 items）; prevention and treatment of major com- plications （12 items）; and rehabilitation （four items）. This is the first time that Chinese experts have published a consensus on spine and spinal cord injury. The expert consensus was established based on Delphi methods, literature analysis, and clinical experiences. Each recommendation is supported by and was interpreted using multi-level evidences. The level of agreement with the rec- ommendation among the panel members was assessed as either low, moderate, or strong. Each panel member was asked to indicate his or her level of agreement on a 5-point scale, with ＂1＂ cor- respondJng to neutrality and ＂5＂ representJng maxJmum agreement. Scores were aggregated across the panel members and an arithmetic mean was calculated. This mean score was then translated into low, moderate, or strong. After all of the votes were collected and calculated, the results showed no low-level recommendations, 10 moderate-level recommendations, and 44 strong-level recom- mendations. An expert consensus was reached and was recognized by Chinese spine surgeons. Wide-scale adoption of these recommendations is urgent in the management of acute thora- columbar spine and spinal cord injury in a broader attempt to create a standard evaluation and treatment strategy for acute thoracolumbar spine and spinal cord injury in China.
