Facile preparation of Sn-doped BiOCl photocatalyst with enhanced photocatalytic activity for benzoic acid and rhodamine B degradation

Non-stoichiometric SnS microspheres with highly enhanced photoreduction efficiency for Cr(vi) ions

“…This may have originated from the formation of a discrete energy state below the conduction band that decreased the photonic excitation energy required for charge carrier transition. 24 Accordingly, the band gap would have decreased, explaining why Sn 2+ doping improved photocatalytic performance. However, when the Sn 2+ dopant concentration further increased, the band gap increased slightly, though it was still lower than that of the parent un-doped SnS.…”

“…Notably, self-doped Sn acts as a donor ion and provides high electron carrier concentrations, thereby facilitating photocatalytic-Cr(VI) reduction. 10,24 Introduction of Sn dopant into SnS via non-stoichiometric synthesis helped to decrease the band gap of the parent material, which enabled doping; this is an important feature in tuning photocatalytic performance. While conventional photocatalyst synthesis generally employs a template to modulate the shape of the photocatalyst, such as a surfactant or stabilizer, the method presented in this work allows for the synthesis of surface-textured SnS microspheres without the need for a template and involves a simple singlestep hydrothermal synthesis with a yield greater than 95%.…”

Facile one‐step synthesis of Nd‐doped BiOCl nanoparticles with the excellent photocatalytic behavior

“…From the results, it was observed that all the synthesized materials shown alike peak position; however, 1% doped BiOCl displayed much weaker emission intensity compared with pure and 2% Nd‐doped BiOCl that may be due to existence of the oxygen vacancies and interstitial Bi 3+ . The results reveal that the presence of optimum amount of doping ions can restrain recombination of photoinduced electron and hole pairs and resulted in increased photon efficiency …”

“…The optically and structurally modified materials have given better performance than regular material. Among them, doping of BiOCl with metal and non‐metal has been identified as an alternate route to modify the optical and structural properties of the semiconducting material . Meichao Gao et al reported a significant positive effect on photocatalytic acivity of BiOCl, which has been modified with Fe .…”

Synthesis of quadrangular bismuth oxychloride NFs for the reduction of 4‐NP and the degradation of rhodamine B

“…It is also the first synthetic non-toxic pearlescent pigment. BiOCl is widely used in photocatalysts [1,[6][7][8][9][10], gas sensitive materials and pearlescent pigments [11]. Moreover, the specific structure, morphology and composition of BiOCl have different optical, electrical and catalytic properties [12,13].…”
