“…XRD patterns of CuCl-modified diatomite samples are presented in Figure 1. In the XRD pattern of diatomite appeared the peak at 21.98°, which is characteristic for cristobalite of diatomite phase [32,33]. In XRD patterns of CuCl-modified diatomites, the peaks at 28°, 33°, 45°, and 56°were assigned to (111), (200), (220), and (311) of CuCl phase, respectively [34].…”

An atomic implantation method was used to modify diatomite with CuCl. The CuCl/diatomite samples were characterized by different techniques, including FTIR, XRD, BET, SEM-TEM, EDX, and CO-TPR. Characterization results revealed the formation of CuCl particles of 50–60 nm highly dispersed on diatomite surface. CO adsorption measurements showed that 2CuCl/diatomite exhibits the highest CO adsorption capacity among all CuCl-modified samples with diatomite. Its CO adsorption capacity of 2.96 mmol/g at 30°C is 10 times higher than that of unmodified diatomite (0.29 mmol/g). The CO adsorption on CuCl-modified diatomites was found to fit well with the Langmuir–Freundlich model.

“…The corresponding first-order kinetics plot shown in Figure 4 c,d demonstrated that the 40B25/CN composite shows superior formaldehyde purification performance under sunlight and the degradation efficiency was higher than of pure BiOCl. The K value of 40B25/CN (0.0133 min −1 ) was 1.32 times higher than that of B25 (0.0101 min −1 ) [ 23 , 24 ], further indicating that the introduction of NC-Na-3.0 significantly improves the photocatalytic performance of BiOCl.…”

Binary composite was synthesized via coupling BiOCl with alkali leached natural clinoptilolite (40B0/CN), which showed retarded recombination of photo-generated carriers. The clinoptilolite was pretreated with alkali leaching, resulting in a larger pore size and high cation exchange capacity. The modified clinoptilolite was more feasible for the growth of BiOCl and to promote the adsorption ability for formaldehyde (HCHO). In addition, the cation exchange capacity was conducive to anchor Bi3+, further leading to the reduction of the particle size of BiOCl. The carrier effect of alkali leached natural clinoptilolite promoted the amorphous transformation of BiOCl at low temperature, which simultaneously produced more distortions and defects in the BiOCl lattice. The 40B0/CN composite exhibited the superior light absorption ability with a narrower band gap. The photocatalytic degradation rate for HCHO of 40B0/CN under solar light reached 87.7%, and the reaction rate constant was 0.0166 min−1, which was 1.6 times higher than that of BiOCl. This paper gave a deep insight into photocatalytic technology to efficiently degrade formaldehyde.

The construction and regulation of heterogeneous interfaces are beneficial to improve solar light harvesting and photocharge separation of hybrid BiOCl-based photocatalysts, which are attributed to the synergistic effects that originate from the integrated interaction between disparate components. With the rapid development of synthetic technologies, hybrid BiOCl-based micro-/nanostructures with diversified components, morphologies, and sizes have been well prepared. Moreover, hybrid BiOCl-based photocatalysts have presented a promising potential for various photocatalytic applications, such as organic pollutant degradation, hydrogen production, NO removal, CO2 reduction, heavy metal ion detection, disinfection, nitrogen fixation, and alcohol oxidation. Previously, several review articles have mainly summarized the advances made in synthetic methods, morphological control, modification strategies, and applications of the bare BiOCl micro-/nanostructures. However, a comprehensive overview based on the type of species and the corresponding correlations between microstructures, performances, as well as photocatalytic mechanisms has been less reported for hybrid BiOCl-based photocatalysts so far. Therefore, a comprehensive understanding of the basic theory and research progress of hybrid BiOCl-based photocatalysts is imperative. This review aims to provide an overview of the important advances made in eight types of hybrid BiOCl-based photocatalysts, including metal/BiOCl, metal oxide/BiOCl, metal sulfide/BiOCl, BiOX (X = Cl, Br, I)/BiOCl, AgX (X = Cl, Br, I)/BiOCl, organics/BiOCl, carbon/BiOCl, and other BiOCl-based multicomponents. In each classification, the synthetic methods, modification strategies, relationships between interfacial microstructures, and enhanced performances are discussed based on some typical examples. Additionally, some scientific issues and potential directions are also given. Hopefully, this review paper will provide a useful reference for researchers currently focusing on exploring new BiOCl-based photocatalysts.
