Abundant oxygen vacancies and strong interfacial electronic effects of ultra-low Pt-loading catalysts (Pt/MoO _x -H) drive efficient chemoselective hydrogenation of nitroarenes.

Purification of organic impurities is critical for electronic-grade hydrogen peroxide (E-H₂O₂), since residual organics severely deteriorate the performance of semiconductor devices. Herein, we report a carbon-based sorbent (BAC-x) constructed via sodium metaborate (NaBO₂), which shows outstanding organic impurities removal efficiency in 27.25 wt% and 38.84 wt% H₂O₂ solutions. Structure characterizations reveal that NaBO₂ modification effectively tailors the surface chemical environment of activated carbon by introducing abundant surface functional groups, which act as active adsorption sites and promote chemisorption between the sorbent and organic impurities. Temkin adsorption isotherm and pseudo-second-order kinetic models confirm that surface chemical environment governs the rate-limiting adsorption step. As a result, BAC-800 exhibits an exceptional organic impurities removal efficiency of 96.28% with a residual total organic carbon (TOC) of 6.38 mg·L^-1 that meets the standard of E-H₂O₂.

Synergistic effects of cyano groups, K ⁺ ions and nitrogen vacancies enabled KCN to exhibit outstanding H ₂ O ₂ photosynthesis performance.

Visible-light-driven O ₂ activation is an appealing and sustainable approach for H ₂ O ₂ production.

Noble metal-free electrocatalysts have received widespread attention in a hydrogen evolution reaction (HER) due to the importance of renewable energy development. Herein, a Co₂P/CoP heterojunction embedded on an N-doped carbon (Co₂P/CoP/NC) electrocatalyst was prepared via an in situ pyrolysis method. The as-prepared electrocatalyst exhibited efficient electrocatalytic activity for HER in an acidic solution. The Co₂P/CoP/NC catalyst displayed an overpotential of 184 mV at 10 mA cm⁻² and a low Tafel slope of 82 mV dec⁻¹, which could be attributed to the tight Co₂P/CoP heterojunction and the synergetic effect of Co₂P/CoP and N-doped carbon. In addition, the electrochemical active surface area of Co₂P/CoP/NC was 75.2 m² g⁻¹, which indicated that more active regions can be applied for the HER process. This report may pave a new way for the design of efficient and low-cost N-doped-carbon-supported 3d transition metal phosphide electrocatalysts.
