“…The higher performance of metal-doped TiO 2 could be attributed to the synergistic effect among metals and TiO 2 and improved charge separation with the mono-and bimetal doping. [28][29][30] Furthermore, maximum performance exhibited by the BZT4 catalyst could be attributed to its most suitable bandgap energy for photon capture in UV light (Table 1) and highest charge separation as confirmed by PL spectra in Fig. 7.…”

BACKGROUNDCommercial TiO2 nanoparticles were subjected to modification through Bi and Zn metal doping. The resulting catalysts were comprehensively characterized, and their performance was then reviewed for removal of model pollutant nitrobenzene in water.RESULTSAmidst the synthesized catalysts, the co‐doping of Bi/Zn (0.25:0.75 wt%) demonstrated the best photocatalytic degradation activity, achieving 95% degradation within 90 min of reaction time, with 2.99 × 10−2 min−1 rate constant value. The involvement of different radicals during the degradation process was elucidated by employing appropriate radical scavengers. Furthermore, the degradation results were investigated applying the first‐order kinetic model, leading to the determination of reaction rate constants and initial rates of the degradation process.CONCLUSIONAn improved photocatalytic activity was observed with metal doping due to the synergistic effect of doped metals with commercial TiO2 and profound charge transfer among them. It was observed that performance was increased with temperature rise in the practical range of application, that is, 5–20 °C. This behavior was due to high rate of movement of charge carriers. Further, involvement and functioning of various radical species such as h+, OH− and O2− in nitrobenzene degradation were successfully established using appropriate radical scavengers. © 2024 Society of Chemical Industry (SCI).

Even if a newly developed catalyst is super excellent, commercialization will not be achieved without a molding technology. Unfortunately, the thermal-instability catalyst is infeasible to be extruded since an afterward calcination is necessary to increase the mechanical strength. Thus, a coating technology is a necessity. In this work, an easy coating method was put forward. In brief, catalyst powder was pretreated by ball milling and coated on to a cordierite before being stabilized at 105 °C. When the coating thickness was increased from 23.89 to 30.59 μm, the internal diffusion resistance (R in ) for catalytic oxidization of chlorobenzene was increased from 0.93 to 1.37 s•m −1 at 200 °C. Although a higher catalytic temperature (350 °C) decreased the R in from 1.37 s•m −1 to 0.62 s•m −1 , the energy consumption was relatively huge. In comparison to increasing the temperature, increasing the effective thickness of the coating was preferable. As for the VW/Ti catalyst used in this work, the preferred powder content in the coating slurry was 40−45 wt % together with a coating rate of 13−14 wt %. The catalyst-powder size and weight percentage in the slurry determined both adhesive force and pore amount in the formed coating layer. The main result of this work is in favor of commercializing a temperature-sensitive catalyst.

Human production and living processes emit excessive VOCs into the atmosphere, posing significant threats to both human health and the environment. The photothermal catalytic oxidation process is an organic combination of photocatalysis and thermocatalysis. Utilizing photothermal catalytic degradation of VOCs can achieve better catalytic activity at lower temperatures, resulting in more rapid and thorough degradation of these compounds. Photothermal catalysis has been increasingly applied in the treatment of atmospheric VOCs due to its many advantages. A brief introduction on the three modes of photothermal catalysis is presented. Depending on the main driving force of the reactions, they can be categorized into thermal‐assisted photocatalysis (TAPC), photo‐assisted thermal catalysis (PATC) and photo‐driven thermal catalysis (PDTC). The commonly used catalyst design methods and reactor types for photothermal catalysis are also briefly introduced. This paper then focuses on recent developments in specific applications for photothermal catalytic oxidation of different types of VOCs and their corresponding principles. Finally, the problems and challenges facing VOC degradation through this method are summarized, along with prospects for future research.
