“…This topographical characteristic closely resembles that of BOC-CNFM reported in prior research. 23 The majority of BNs exhibit a square shape, and the lamellar membranes consist of BNs arranged layer-by-layer in an organized manner, featuring vertical channels between the edges of the BNs. The high-resolution transmission electron microscopy (HRTEM) image of BNs from a top view reveal a lattice spacing of 0.27 nm, indicative of the (110) atomic plane (Fig.…”

Biopolymer-based catalysts like chitosan, chitin, and cellulose offer sustainability and high efficiency both as the catalyst or catalyst support in a broad range of applications, especially in hydrogen evolution reactions. This review focused on hydrogen evolution catalysts of chitosan, chitin, cellulose, and carbon materials obtained from these biopolymers to highlight the opportunities of these sustainable catalysts in this field. All the reports in this area could be classified as one of the photocatalysts, electrocatalysts, and photoelectrocatalysts, and their mechanisms were clarified in the beginning. Then, the results of catalysts obtained from each of these biopolymers were discussed separately to reveal the roles of the biopolymers. It was concluded that all of the biopolymers enjoy some common benefits like hydrogen bonding, chelating with transition metals, easy chemical modification, high performance, and potential to be used as the precursors of carbon or porous materials. Among them, chitosan showed outstanding merit due to the better performance in metal grafting, amendment, and ability of hydrogen bonding. Moreover, it provides highly active nitrogen-doped carbon as the support of transition metals in the hydrogen generation, enhancing the reaction rate by retarding the charges recombination.

“…Although the optical absorption properties of modified BiOCl clearly extend into the visible region, the degradation rate is very slow, taking several hours to reach more than 80%, which does not favor the widespread adoption of photocatalysis in addressing environmental contamination. 24,26,28,29 Recently, there have been articles exploring the structural modifications of BiOCl, 27,30 for example, preparation of flowerlike, spheroidal, lamellar, and filamentous BiOCl, 29,31,32 as well as modification of BiOCl crystal surface. 15,33 degradation activity of BiOCl.…”

BiOCl photocatalyst with excellent performance has been prepared by a simple liquid−solid phase transition method. Three BiOCl-x (x = 0.5, 0.75, 1.0) photocatalysts were obtained by changing the amount of HCl in the preparation process. The main dominant crystal planes are (001), (002), and (003). Their forbidden bandwidths are reduced to 2.81, 2.89, and 2.84 eV. The samples were characterized by X-ray diffractometer, high-resolution field emission scanning electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier infrared spectrometry, UV−vis diffuse reflection spectrometer, and UV−vis spectrophotometer. The degradation mechanism of BiOCl-x on Rhodamine B(RhB) has been investigated by quenching experiments on active materials. •O 2 − was the primary degradation agent. When the dosage of HCl was 0.75 mL, the degradation effect of RhB was the best under the same experimental conditions. In visible light, RhB was almost completely degraded within 15 min, demonstrating an excellent photocatalytic degradation efficiency.
