Sustainable Furfural Biomass Feedstocks Electrooxidation toward Value-Added Furoic Acid with Energy-Saving H_(2) Fuel Production Using Pt-Decorated Co_(3)O_(4) Nanospheres

引用

Energy & Environmental Materials 2024年第2期7卷 350-358页

Here,furfural oxidation was performed to replace the kinetically sluggish O_(2)evolution reaction(OER).Pt-Co_(3)O_(4)nanospheres were developed via pulsed laser ablation in liquid(PLAL)in a single step for the paired electrocatalysis of an H_(2)evolution reaction(HER)and furfural oxidation reaction(FOR).The FOR afforded a high furfural conversion(44.2%)with a major product of 2-furoic acid after a 2-h electrolysis at 1.55 V versus reversible hydrogen electrode in a 1.0-M KOH/50-mM furfural *** Pt-Co_(3)O_(4)electrode exhibited a small overpotential of 290 mV at 10 mA cm^(-2).As an anode and cathode in an electrolyzer system,the Pt-Co_(3)O_(4)electrocatalyst required only a small applied cell voltage of~1.83 V to deliver 10 mA cm^(-2),compared with that of the pure water electrolyzer(OER||HER,~1.99 V).This study simultaneously realized the integrated production of energy-saving H_(2)fuel at the cathode and 2-furoic acid at the anode.

Surface-phonon-polariton-enhanced photoinduced dipole force for nanoscale infrared imaging

引用

National Science Review 2024年第05期 227-235页

作者： Jian Li Junghoon Jahng Xuezhi Ma Jing Liang Xue Zhang Qianhao min Xiao-Liang Wang Shuangjun Chen eun Seong Lee Xing-Hua Xia State Key Lab of Analytical Chemistry for Life Science School of Chemistry and Chemical Engineering Nanjing University Hyperspectral Nano-Imaging Team Korea Research Institute of Standards and Science Institute of Materials Research and Engineering Agency for ScienceTechnology and Research College of Materials Science and Engineering Nanjing Tech University

The photoinduced dipole force(Pi DF) is an attractive force arising from the Coulombic interaction between the light-induced dipoles on the illuminated tip and the sample. It shows extreme sample-tip distance and refractive index dependence, which is promising for nanoscale infrared(IR) imaging of ultrathin samples. However, the existence of Pi DF in the mid-IR region has not been experimentally demonstrated due to the coexistence of photoinduced thermal force(Pi TF), typically one to two orders of magnitude higher than Pi DF. In this study, we demonstrate that, with the assistance of surface phonon polaritons, the Pi DF of c-quartz can be enhanced to surpass its Pi TF, enabling a clear observation of Pi DF spectra reflecting the properties of the real part of permittivity. Leveraging the detection of the Pi DF of phonon polaritonic substrate, we propose a strategy to enhance the sensitivity and contrast of photoinduced force responses in transmission images, facilitating the precise differentiation of the heterogeneous distribution of ultrathin samples.
