Construction of ternary RuP₂/Ti₄P₆O₂₃@TiO₂ photocatalysts for efficient photocatalytic biomass selective oxidation and water splitting

Abstract

High-efficiency visible-light-driven biomass conversion coupling with water splitting has attracted considerable attention, but the achievements have been rather limited. Here, the ternary RuP2/Ti4P6O23@TiO2-7 photocatalyst was successfully constructed for efficient simultaneously...

Iron-doping-induced formation of Ni–Co–O nanotubes as efficient bifunctional electrodes

“…Electrochemical water splitting is considered an efficient approach to produce hydrogen and oxygen. [1][2][3][4] The key factors affecting the performance of overall water splitting are determined by the efficiencies of the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Generally, the theoretical thermodynamic voltage needed for water electrolysis is 1.23 V. 5,6 However, due to the sluggish kinetics, the water splitting reaction commonly requires a much larger operating voltage of 1.6-2.0 V, 5 resulting in much more energy consumption, and hindering its practical application.…”

Building internal electric fields in porous ionic polymers for fast photocatalytic degradation of tetracycline hydrochloride

“…[3][4][5] Great efforts have been devoted to tailor the photocatalysts to enhance the solar energy conversion efficiency. [6][7][8] However, the intrinsically strong propensity of charge/carrier recombination results in difficulties for chargeinduced degradation of antibiotic contamination. [9][10][11][12] Currently, the surface engineering approaches to build the internal electric field (IEF), including heterojunctions, 13,14 phase junctions, [15][16][17][18] facet junctions, 19,20 co-catalyst loading 21 have been developed to spatially separate photogenerated hole-electron (h + -e À ) pairs, thereby enhancing the photocatalytic performance.…”
