“…The close interaction between platinum clusters and nickel clusters leads to homogeneous reduction, forming Pt-Ni alloy. In addition, the size of metal particles decreases to 13 nm in the presence of Pt, indicating that the addition of Pt results in higher dispersion of Pt-Ni particles, as same as the effect of addition of Ce (Li et al, 2017). The Pt-enriched alloy surface can inhibit the oxidation of nickel and suppress the leaching of active nickel, which leads to excellent hydrothermal stability.…”

With the demand of energy and re-utilization of wastes, the renewable lignocellulosic biomass, has attracted increasing and significant attention for alleviating the growing energy crisis and environment problems. As main components of lignocellulosic biomass, lignin, cellulose, and hemicellulose are connected by hydrogen bond to form a compact skeleton structure, resulting the trenchant condition of biomass pyrolysis. Also, pyrolysis products of above three main constituents contain a large amount of oxygenates that cause low heating value, high corrosiveness, high viscosity, and instability. Meanwhile, zeolites are of considerable significance to the conversion of lignocellulosic biomass to desirable chemical products on account of fine shape selectivity and moderate acid sites and strength. Among numerous zeolites, ZSM-5-based catalysts have been most extensively studied, and the acidity and porosity of ZSM-5 can be tuned by changing the content of Si or Al in zeolite. Beyond that, doping of other metal elements, such as Mn, Co, Ni, Ga, Ce, Pt, into ZSM-5 is also an efficient way to regulate the strength and density of acid sites in zeolite precisely. This review focused on the recent investigation of Ni-modified microporous ZSM-5 used in catalytic pyrolysis of lignin and cellulose. The application of metal-modified hierarchical ZSM-5 is also covered.

“…Burning of these fuels releases vast amount of CO 2 , CO, unburned hydrocarbons, NO x , NH 3 , and SO x in the atmosphere which have adverse effects on global climate, ecological systems, and animal health and also resulting in freak weather, desertification of land, sea‐level rise, and widespread extinctions of plants, amphibians, and other terrestrial and aquatic lives . Because of the depletion of fossil fuels and environmental issues related with carbon emission, H 2 is believed as an alternative source to fill the gap between increasing future energy demand and fast depletion of fossil fuels while trying to control carbon emission to the environment caused by the combustion of fossil fuel‐based raw materials …”

“…The pioneering work of Honda and Fujishima drew the attention of the mass toward the solar water splitting when they used a single crystal of rutile titanium dioxide as a photoanode to split water (H 2 and O 2 ) photo‐electrochemically called Honda–Fujishima effect 23b. Later on, a considerable amount of scientific research went underway and still under process to develop low cost, efficient, stable, economical, and environment‐friendly materials to precede the photochemical water splitting reaction for the sake of energy requirement in the form of H 2 with ease and enhanced productivity.…”

The surface plasmon resonance (SPR) of noble metals is known to improve the efficiency of various processes and devices. The photocatalytic process is the production of fuels and storage of solar photons in chemical bonds without imposing harmful threats to the environment. Photovoltaics are other devices utilizing solar energy for electrical energy. Similarly, other optoelectronic devices like photodetectors absorb photons and convert it into charges via electron–hole dissociation processes. In contrast, light‐emitting optoelectronic devices work based on the phenomenon of charge recombination to produce light. All these devices, however, have efficiency limitations, which impede the application of novel functional materials in these devices. A more direct approach is the utilization of noble metals and their complexes, which significantly enhance the efficiencies of these devices by SPR. This article highlights recent works and applications of noble metals by SPR‐enhanced photocatalysis for hydrogen evolution from water, CO2 conversion into useful compounds, and oxidation of hazardous pollutants. In addition, the plasmon‐enhancement of optoelectronic devices is summarized. Several possible mechanisms that have been previously reported in the literature are discussed in this work, with particular emphasis on different features of these mechanisms involving devices that are not highlighted and therefore need more attention.

With the depletion of non-regenerated energy and the increasing awareness of environmental protection, renewable energy developing has become a key subject of research. Hydrogen as a kind of clean energy has aroused much attention. In this study, hydrogen production from bio-oil derived phenolic compound in aqueous phase was studied. Hydrotalcite-derived Ni/Zn/Al catalysts with different metallic compositions were synthesised and screened for aqueous-phase reforming (APR) of phenol. The physiochemical characterisations of hydrotalcite-derived Ni/Zn/Al samples were detected by X-ray powder diffraction (XRD), scanning electron microscope (SEM), fourier transform infrared spectroscopy (FTIR) and N 2-sorption. In the calcined hydrotalcite-derived Ni 5.3 /Zn 2.7 /Al samples, most of the metal oxides exist in the form of rock solid and wurtzite type phase. In order to optimise the reaction condition of APR of phenol, the impacts of initial phenol concentration, reaction pressure and reaction temperature during the APR of phenol were investigated. It was found that increasing the concentration of phenol could enhance the side reaction and decrease the selectivity of hydrogen, while enhancing the reaction pressure was not favourable for hydrogen production. Moreover, proper reaction temperature was necessary for APR of phenol to produce hydrogen over hydrotalcite-derived Ni/Zn/Al catalysts.
