“…TiO 2 , with a bandgap energy of about 3.2-3.35 eV, corresponding to a wavelength of 380 nm, has been extensively tested for its photocatalytic activity [76,77]. However, since TiO 2 has a high e − /h + recombination rate and is active only in the UVA range, it is a poor photocatalyst for applications such as water splitting [78]. Similarly, Zinc oxide (ZnO), cuprous oxide (Cu 2 O), cerium oxide (CeO 2 ), and cadmium sulfide (CdS) are other commercially available potential photocatalysts; however, the bandgap energy of ZnO, CuO, CeO 2 , and CdS is 3.3-3.5, 2.1-2.5, 2.9-3.4, and 2.4-2.6 eV, respectively, which are not in alignment with thermodynamic energy requirements of applications such as direct solar water splitting or MSR [56, 75-77, 79, 80].…”

Green hydrogen is the energy carrier set in the roadmap to achieve the net zero target. However, hydrogen as the future energy vector, either in compressed gaseous form or liquefied form, demands a complete overhaul of storage and transportation infrastructure at a global scale. Methanol is one of the commercially viable hydrogen carriers that can overcome the infrastructure challenges associated with the storage and transportation of hydrogen. As a sustainable hydrogen carrier, methanol must be reformed to hydrogen prior to the point of usage. This review begins with a detailed discussion on thermocatalytic methanol reforming, catalysts, operating conditions, and the associated challenges for both stationary and mobility applications. An in‐depth analysis of the existing commercial methanol reformers available for on‐board and onsite hydrogen generation is also presented. The current state of the research‐level photo‐ and electroreforming as a possible alternative to thermocatalytic reforming is reviewed and concludes with the future prospects for methanol reforming.

The heavy metal contamination of water systems has become a major environmental concern worldwide. Photocatalysis using metal-organic frameworks (MOFs) has emerged as a promising approach for heavy metal remediation, owing to the ability of MOFs to fully degrade contaminants through redox reactions that are driven by photogenerated charge carriers. This review provides a comprehensive analysis of recent developments in MOF-based photocatalysts for removing and decontaminating heavy metals from water. The tunable nature of MOFs allows the rational design of composition and features to enhance light harvesting, charge separation, pollutant absorptivity, and photocatalytic activities. Key strategies employed include metal coordination tuning, organic ligand functionalization, heteroatom doping, plasmonic nanoparticle incorporation, defect engineering, and morphology control. The mechanisms involved in the interactions between MOF photocatalysts and heavy metal contaminants are discussed, including light absorption, charge carrier separation, metal ion adsorption, and photocatalytic redox reactions. The review highlights diverse applications of MOF photocatalysts in treating heavy metals such as lead, mercury, chromium, cadmium, silver, arsenic, nickel, etc. in water remediation. Kinetic modeling provides vital insights into the complex interplay between coupled processes such as adsorption and photocatalytic degradation that influence treatment efficiency. Life cycle assessment (LCA) is also crucial for evaluating the sustainability of MOF-based technologies. By elucidating the latest advances, current challenges, and future opportunities, this review provides insights into the potential of MOF-based photocatalysts as a sustainable technology for addressing the critical issue of heavy metal pollution in water systems. Ongoing efforts are needed to address the issues of stability, recyclability, scalable synthesis, and practical reactor engineering.

“…The main ways of plasmon effect of metal NPs on the photocatalytic activity of various semiconductor structures consists in increased light absorption efficiency in a wider spectral range [19,20], enhanced the quantum efficiency of electron-hole pair (EHP) generation in a semiconductor material [7], injection of hot electrons and plasmon-induced resonant energy transfer (PIRET) from metal NPs into a semiconductor [18,19,21]. The prevalence of one or another mechanism depends both on the properties of the semiconductor and plasmon NPs themselves, and on their mutual configuration.…”

In this work, the plasmonic effect of Au and Ag nanoparticles in the heterostructure photocatalyst system (TiO2/rGO) was studied. The laser ablation approach was applied to synthesize Au and Ag nanoparticles to eliminate impurity influence in this plasmonic study. Characterizing tools such as SEM, TEM, XRD, Raman, UV–vis spectral techniques were applied to obtain morphological information and optical properties of the nanocomposites. Photocatalytic properties of ternary nanocomposities such as, TiO2/rGO/Ag and TiO2/rGO/Au, were evaluated against Methylene blue and Congo red dyes with changing concentration of plasmonic nanoparticles (Au and Ag) and it was founded that the nanocomposite with the concentration of 10–11 mol/L Au NPs in TiO2/rGO has the best photocatalytic activity. EIS study indicated that a significant decrease in resistance Rp (109 Ohms) was observed for TiO2/rGO at 10-11 mol/Lconcentration of Au and its lifetimes is 0.0118 s, supporting that TiO2/rGO/Au has the best photocatalytic activity at 10–11 mol/L Au in the TiO2/rGO nanocomposites.
