Refractory sulfur compounds especially dibenzothiophene (DBT) encounter removal difficulty by traditional techniques; namely, hydrodesulfurization (HDS) and solvent extraction. To achieve enhanced removal of such sulfur compounds, this study introduces three Bi-based perovskite-like pyrochlore structures as novel photocatalysts for disposal of DBT using model diesel fuel. Bi-Ce ((BCO) and Bi-Zr (BZO) perovskites-like as well as their interfacial heterojunctioned composite (BCO@BZO), 1:1 by molar ratio, were synthesized during this research work. Structural, morphological, textural, and optoelectronic characteristics of the presented perovskite-like were comprehensively investigated via different analytical tools of analyses. The three structures showed reasonable adsorptive desulfurization, observing a maximum removal of 28% by the composite perovskite-like. Upon their usages in photocatalytic desulfurization, the removal efficiency increased by the three structure, however, the maximum (40%) was observed for BCO@BZO. This composite subsequently revealed a strong desulfurization behavior through testing different operating variables, including photocatalyst dose, reaction time, and initial concentration of DBT.

However, the enhanced water dissociation enabled by Ru may be accompanied by excessive adsorption of the adsorbed hydroxyl (OHad), leading to active-site blocking and limited overall HER activity. Here, a dual cation-doping strategy was proposed to balance water dissociation with OHad desorption. Specifically, a Ni/Ru-modified spinel Co3O4 electrocatalyst (NiRuCoOx) has been developed and demonstrated high efficiency for HER and water splitting. Dual metal incorporation induced oxygen vacancies and charge redistribution, thereby modulating the metal-oxygen covalency and weakening the strong interaction between active sites and OHad during the HER process. As a consequence, NiRuCoOx delivered a low HER overpotential of 29 mV at 10 mA cm−2. It also exhibited good performance in oxygen evolution reaction (OER, 270 mV overpotential at 10 mA cm−2). For overall water splitting, the NiRuCoOx bifunctional electrode could reach 10 mA cm−2 with a low voltage of 1.538 V.

Among various candidates, β-PbO2 stands out as a proven ozone catalyst; however, its widespread implementation is severely hindered by sluggish kinetics and poor selectivity. Herein, we report a Ni-mediated electrocrystallization strategy that perturbs the local Pb–O environment within the β-PbO2 framework without appreciable Ni incorporation into the final catalyst. Synchrotron x-ray absorption spectroscopy (XAS), combined with x-ray diffraction (XRD) and x-ray photoelectron spectroscopy (XPS), suggests the presence of lattice strain, electronic-state redistribution, and enhanced local structural disorder. These coupled geometric and electronic changes are consistent with enhanced lattice-oxygen participation during EOP. Consequently, the lattice oxygen-activated PbO2 (Oact-PbO2) exhibits an O3 yield of 425.6 mg h−1 gcat−1 (a 4.21-fold enhancement over pristine PbO2) and a Faradaic efficiency of 14.73% at 2.5 V versus Ag/AgCl. Notably, an O3 concentration of 12.30 mg L−1 is achieved within 5 min, and the electrode maintains stable operation for 300 h at 100 mA cm−2. Furthermore, we establish a rapid and reliable analytical protocol for the quantification of electrogenerated O3.

In response to these limitations, externally applied physical fields have emerged as promising strategies to enhance catalytic efficiency. These fields enable rapid and volumetric energy transfer through mechanisms such as Joule heating, magnetothermal effects, and microwave irradiation, thereby reducing energy consumption and shortening startup times. Beyond thermal effects, externally applied fields also induce non-thermal interactions that modify the electronic structure of catalysts, facilitating reactant adsorption and activation while lowering reaction energy barriers. As a result, these synergistic thermal and non-thermal effects contribute to enhanced low-temperature catalytic activity, a broader operating temperature window, and improved resistance to catalyst deactivation. Accordingly, this review systematically summarizes recent advances in field-assisted catalysis, with particular emphasis on both mechanistic insights and practical applications in pollutant degradation.
