FeVO₄ nanowires for efficient photocatalytic CO₂ reduction

Abstract

Photocatalytic CO2 reduction is of great significance for alleviating environmental pollution and energy shortages. Double transition metal oxide semiconductors are a commonly used material library in the field of photocatalysis....

A novel aqueous zinc-ion battery capable of self-charging at low temperature

“…Specifically, the peak at 529.5 eV corresponds to lattice oxygens, the peak at 530.5 eV is associated with surface adsorbed hydrocarbons, and the peak at 531.65 eV represents the defects of O 2− vacancies in the FVO cathode film. 34,35…”

“…Specically, the peak at 529.5 eV corresponds to lattice oxygens, the peak at 530.5 eV is associated with surface adsorbed hydrocarbons, and the peak at 531.65 eV represents the defects of O 2− vacancies in the FVO cathode lm. 34,35 A coin cell is constructed with an FeVO 4 $H 2 O cathode, a zinc anode, and an electrolyte comprising 1 m Zn(CF 3 SO 3 ) 2 and 5.16 m LiTFSI. To investigate its kinetic behavior, cyclic voltammetry (CV) measurements are performed at 25 °C and 0 °C.…”

Facile synthesis of neodymium vanadate nanoribbons and its application to highly efficient determination of cadmium ions

“…Although the present electrode materials show improved stripping signals and electrochemical sensing performance for cadmium ion detection, it is still essential and urgent to seek new nanoscale electrode materials for developing a highly sensitive and antifouling cadmium ion sensing platform. Rare metal vanadates possess good catalytic performance for electrocatalysis of the water oxidation reaction (polyoxovanadates), 40 photocatalytic oxidation of methane (nanoscale bismuth vanadate), 41 photocatalytic degradation of organic pollutants (nanoscale pillar‐like, dendrites and microgranular bismuth vanadate), 42 photocatalytic reduction of CO 2 (FeVO 4 nanowires), 43 electrochemical and lithium storage performance (copper vanadate nanowire arrays) 44 owing to their advantages of attractive electrochemical redox properties, chemical inertness, broad useful potential range, low cost, great versatility and easy modification. Neodymium vanadate belongs to a kind of important rare metal vanadate, showing good catalytic, optical and ferrimagnetic properties 45‐47 .…”
