Abstract Strain engineering is an effective strategy in modulating activity of electrocatalysts, but the effect of strain on electrochemical stability of catalysts remains poorly understood. In this work, we combine ab initio thermodynamics and molec

Oxygen vacancies in metal oxides can serve as electron trap centers to capture CO2 and lower energy barriers for the electrochemical CO2 reduction reaction (CO2RR). Under aqueous electrolytes, however, such charge-enriched active sites can be occupie

MOx-biochar (Mox = Cu, Co, Mn or Ni oxides) supported materials were prepared, characterised and tested in the reduction of 4-nitrophenol to 4-aminophenol employing sodium borohydride as reducing agent. The catalyst/reducing agent optimal ratio was d

A series of 20 wt.% MO2/S catalysts (where M = Ce, Mn or Zr and S = SiO2 or Al2O3) were prepared using various precursors of the active phases. The resulting catalysts were characterized using different methods (XRD, TPR and SBET). For the first time
