A Zn0.5Cd0.5S Photocatalyst Modified by 2D Black Phosphorus for Efficient Hydrogen Evolution from Water

Abstract: In this work, a photocatalyst composited of Zn 0.5 Cd 0.5 S and 2D black phosphorus (BP) nanosheets was successfully constructed for high-efficient hydrogen evolution. The structure, morphology and chemical composition of BP x /Zn 0.5 Cd 0.5 S photocatalysts were characterized by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), atomic force microscopy (AFM), and X-ray photoelectron spectroscopy (XPS). Remarkably, the hydrogen production rate of optimal BP 15.2 / Zn 0.5 Cd 0.5 … Show more

“…[198] Similarly, BP@TiO 2 hybrid photocatalysts were synthesized to offer enhanced photocatalytic performance and maintain ≈92% photoactivity activity after 15 runs. [201][202][203][204] For example, strong electron doping of BP with Cs 2 CO 3 nanoparticles significantly enhanced the electron mobility to ≈27 cm 2 V −1 s −1 , while surface decoration of BP with MoO 3 nanoparticles demonstrated a giant hole-doping effect. [200] Recently, more BP hybrids were fabricated by using other functional nanomaterials.…”

“…[199] In addition, SrTiO 3 was also hybridized on BP nanosheets to achieve the giant photoresponsivity with a photoinduced current change of more than 10 5 A W −1 . [201] The Zn 0.5 Cd 0.5 S nanoparticles were hybridized onto the pre-produced BP nanosheets via an ultrasonic process to achieve the hydrogen production rate as high as 137.17 mmol g −1 h −1 under the irradiation of visible light, 5 times higher than that for the pristine Zn 0.5 Cd 0.5 S. [202] After enhancing the visible-light photocatalytic activity by using synthesized Z-scheme photocatalytic BP/BiVO 4 heterostructures, [204] the hydrogen and oxygen production rates were increased to ≈160 and ≈102 mmol g −1 h −1 under the irradiation of light with a wavelength longer than 420 nm. [201][202][203][204] For example, strong electron doping of BP with Cs 2 CO 3 nanoparticles significantly enhanced the electron mobility to ≈27 cm 2 V −1 s −1 , while surface decoration of BP with MoO 3 nanoparticles demonstrated a giant hole-doping effect.…”

“…In contrast to bulk BP, the VB level of BP‐BM has been positively shifted which avoids undesirable recombination of the photogenerated electron–hole pairs (Figure b). In addition to this, so far, many other chemically modified BPNSs based photocatalysts have been successfully employed for H 2 evolution reaction, revealing that BPNSs will be a good photocatalyst for energy production to solve the future energy crisis . Besides H 2 evolution reaction, Co 3 O 4 modified BPNSs have been used as an electrocatalyst for oxygen evolution reaction .…”
