BiVO_(4)is one of the most promising photoanode materials for photoelectrochemical(PEc)solar energy conversion,but it still suffers from poor photocurrent density due to insufficient light‐harvesting efficiency(LHE),weak photogenerated charge separation efficiency(Φ_(Sep)),and low water oxidation efficiency(Φ_(OX)).Herein,we tackle these challenges of the BiVO_(4)photoanodes using systematic engineering,including catalysis engineering,bandgap engineering,and morphology *** particular,we deposit a NicoO_(x)layer onto the BiVO_(4)photoanode as the oxygen evolution catalyst to enhance theΦ_(OX)of Fe‐g‐c_(3)N_(4)/BiVO_(4)for PEc water oxidation,and incorporate Fe‐doped graphite‐phase c_(3)N_(4)(Fe‐g‐c_(3)N_(4))into the BiVO_(4)photoanode to optimize the bandgap and surface areas to subsequently expand the light absorption range of the photoanode from 530 to 690 nm,increase the LHE andΦ_(Sep),and further improve the oxygen evolution reac.ion ac.ivity of the NicoO_(x)catalytic ***,the maximum photocurrent density of the as‐prepared NicoO_(x)/Fe‐g‐c_(3)N_(4)/BiVO_(4)is remarkably boosted from 4.6 to 7.4 mA cm^(−2).This work suggests that the proposed systematic engineering strategy is exceptionally promising for improving LHE,Φ_(Sep),andΦ_(OX)of BiVO_(4)‐based photoanodes,which will substantially benefit the design,preparation,and large‐scale application of next‐generation high‐performance photoanodes.

Green Energy & Environment 2024年第3期9卷 573-583页

Lithium-ion capacitors(Lics) combining the advantages of lithium-ion batteries and supercapacitors are considered a promising nextgeneration energy storage device. However, the sluggish kinetics of battery-type anode cannot match the capacitor-type cathode, restric.ing the development of Lics. Herein, hierarc.ical carbon framework(HcF) anode material composed of 0D carbon nanocage bridged with 2D graphene network are developed via a template-confined synthesis process. The HcF with nanocage structure reduces the Li^(+) transport path and benefits the rapid Li^(+) migration, while 2D graphene network can promote the electron interconnec.ing of carbon nanocages. in addition, the doped N atoms in HcF facilitate to the adsorption of ions and enhance the pseudo contribution, thus accelerate the kinetics of the anode. The HcF anode delivers high specific capacity, remarkable rate capability. The Lic pouch-cell based on HcF anode and ac.ive HcF(a-HcF) cathode can provide a high energy density of 162 Wh kg^(-1) and a superior power density of 15.8 kW kg^(-1), as well as a long cyc.ing life exceeding 15,000cycles. This study demonstrates that the well-defined design of hierarc.ical carbon framework by incorporating 0D carbon nanocages and 2D graphene network is an effec.ive strategy to promote Lic anode kinetics and hence boost the Lic electrochemical performance.
