The surface reconstruction of transition metal-based catalysts has been demonstrated to be beneficial for oxygen evolution reaction (OER). However, regulating the activity and stability of the components derived from reconstruction is challenging. Here, a strategy of Fe ion modulating the reconstruction components of CoN on a nitrogen-doped carbon carrier(CoN /NC) electrocatalyst for promoted OER activity and stability is reported.

The catalytic activity of BiO was tested using 4-chlorophenol (4-CP) as the target aqueous pollutant. We observed that 10 ppm of 4-CP was completely degraded within 40 min at a reaction temperature of 65 °C.

Herein, we report a specific bifunctional 2D/2D g-CN/BiO nanosheets heterojunction, prepared through a self-assembly approach. Delightfully, the obtained 2D/2D heterojunctions exhibited satisfactory photocatalytic disinfection performance towards Escherichia coli K-12 (E.

In this study, molybdenum powder (Mo) was applied as the co-catalyst to improve the degradation of 2,4-dichlorophenol (2,4-DCP) in Cu/PMS system at pH 5.6.

In the present study, the co-catalytic effect of WS on the Fe(II)/PMS system for the degradation of organics was investigated. In the presence of WS, Fe(III) was reduced to Fe(II) during the reaction and resulted in improved decomposition of PMS as well as the degradation of 4-chloriphenol (4-CP).
