Abstract The Constructing an efficient and low‐cost oxygen evolution reaction (OER) electrocatalyst is critical for improving the performance of electrolysis in alkaline water. In this study, a self‐supported flower‐like cobalt phosphide tungsten oxide (Co 2 P/WO 3−x /CC) was prepared on carbon cloth (CC) surface by hydrothermal with solution immersion etching phosphorization annealing under H /Ar atmosphere. This strategy can generate vacancies (O V ), speed charge transfer between P) (WO ) components. catalyst greatly increases electrochemical active area, which beneficial evolution. Electrochemical testing studies show that 1.0 M KOH solution, Co P–WO /CC exhibits good OER activity, low overpotential 254 mV at 10 mA cm −2 , small Tafel slope 58.32 dec −1 . synergistic effect P WO regulate electronic structures, expose more sites, cooperatively enhancing activity. study provides workable preparing non‐noble metal electrocatalysts engineered interfaces O

Abstract Traditional synthesis methods for metal phosphides are often inefficient and not environmentally friendly due to complex procedures. Here, we propose an eco‐friendly efficient mechanochemical method phosphide flame retardant through high‐energy ball milling. Specifically, solid red phosphorus Ti₃AlC₂ were directly reacted in the milling jar, producing a hybrid with TiP AlP as main active components (TiP/AlP@C). It demonstrates that TiP/AlP@C exhibited excellent performances, reducing maximum thermal decomposition rate of epoxy resin by 35.3%, carbon monoxide release 29.3%, smoke 11.3%. These findings suggest synthesized primarily exerts its flame‐retardant effect catalyzing formation protective char layer, which acts barrier during combustion. This study confirms effectiveness scientific validity innovative advanced retardants. Highlights Hybrid retardants prepared high energy The speed time crucial reaction. additive is fire hazard resin. A synergistic charring from proposed.
