Construction of novel flower-like functionalized black phosphorus nanosheets/P-doped BiOCl S-scheme photocatalysts with improved photocatalytic activity in RhB and Cr(vi) degradation

Abstract

Photocatalytic degradation has been developed as a promising strategy for environmental remediation. Black phosphorus (BP) has attracted much attention in the field of photocatalysis due to the adjustable bandgap and...

Production of high-quality and large lateral-size black phosphorus nanoparticles/nanosheets by liquid-phase exfoliation

“…As can be seen in the gure, the XRD peak position of the fabricated nanosheets is identical to that of the bulk BP crystal, but the peak intensity differs considerably from that of bulk BP. 38,39 Therefore, the decrease in the XRD peaks of BP nanosheets approves the successful exfoliation of BP through the LPE method.…”

Construction of 2D S‐Scheme Heterojunction Photocatalyst

“…To improve the oxidation ability and charge separation, numerous research works construct BP-based S-scheme heterojunctions by hybridizing BP with oxidation photocatalysts such as WO 3 and BiOX. [154][155][156][157] BP-based S-scheme photocatalysts are widely applied to CO 2 reduction because of the high CB position and strong CO 2 adsorption capacity of BP. [158,159] Recently, a 2D/2D BP/Bi 2 WO 6 S-scheme photocatalyst was fabricated to realize synchronous CO 2 conversion and benzylamine (BA) oxidation.…”

Electron transfer bridge inducing polarization of nitrogen molecules for enhanced photocatalytic nitrogen fixation

“…21,22 These delocalized electrons can then be transferred to the adsorbed reaction molecules through the ''electron transfer bridge''. 23 The electron transfer bridge enables rapid migration of photogenerated electrons to active sites, preventing recombination with holes. This efficient charge separation enhances the photocatalytic efficiency and promotes desirable redox reactions, leading to improved overall performance in various photocatalytic processes.…”
