Highly efficient Bi/BiOCl with oxygen vacancies photocatalyst with synergetic effects of oxygen vacancy, surface plasmon resonance, and electron sink effects of metallic Bi

Applied Organometallic Chemistry, Journal Year: 2024, Volume and Issue: 38(9)

Published: July 8, 2024

Bi/BiOCl with oxygen vacancies composite was synthesized through a facile and rapid in situ surface reduction of BiOCl, utilizing NaBH 4 as the reductant. The process yielded metallic Bi nanoparticles on BiOCl meanwhile created within lattice. As consequence, as‐synthesized composites exhibited substantially enhanced visible‐light absorption capacity, whereas pure only responsive to ultraviolet light. Additionally, demonstrated markedly accelerated photodegradation rate Rhodamine, exceeding that P25 by factor 6.10 19.74, respectively. density functional theory (DFT) calculation carried out estimate band structural electronic properties samples. Based systematic analysis, underlying mechanism attributed extended light range due plasma resonance formation vacancy energy level. Moreover, electron sink effect found suppress recombination photoinduced charges, further contributing photocatalytic performance Bi/BiOCl.

Abstract Developing a product that serves dual purpose as an adsorbent/photocatalyst for ecological applications is compelling study area. This article discusses facile ultrafast synthesis of BiOCl/Bi 2 S 3 /biochar (BiOCl/Bi /BC) by solid-state reaction with coupled roles photocatalyst during sunlight exposure and adsorbent when there no light. /BC was characterized XRD, SEM, EDX, HR-TEM, XPS, FTIR, Raman, DR/UV–Vis spectroscopy techniques. The adsorption efficiency its parameters were explored using ciprofloxacin (CPF) contaminant model drug in the absence light irradiation. role considered under direct 30 achieved removal 81.25% dark reached 90% within 1 h. exhibited triplet initial rate, doubled rate constant photocatalysis (11.34 mg g −1 min , 0.642 ) compared to (3.88 0.256 ), respectively, indicating adsorptive, catalytic, cocatalytic BC. Mechanism studies indicated separated CPF via electrostatic interaction, π – conjunction, hydrogen bonding while occurred through S-scheme mechanism where • O − h + play predominant photocatalytic degradation. Besides, hybrid stable revealed acceptable recyclability after four consecutive cycles from their aqueous solutions. work provided ultrafast, simple, economical, efficient strategy application structure has function elimination water.
