“…The Lewis acid and Brønsted acid sites act cooperatively to impart the catalytic activity.

A new hydraulic cavitation‐assisted epoxidation scheme was developed by using a cost‐effective, environment‐friendly, and recyclable solid‐acid catalyst. SnO2‐Al2O3‐NiO/SO42− solid‐acid catalysts were prepared using co‐precipitation and impregnation methods, which were characterised by several techniques and analysed using the Hammett acidity function. The prepared catalysts were found to have a large specific surface area (53.95 m2/g) and abundant acid sites (94 μmol/g). Exhibits higher stability and more effective catalytic activity compared with H2SO4. Under the optimal reaction conditions, the relative conversion to oxirane of 86.97% was obtained in only 1.5 h of reaction time. Moreover, the catalyst could be easily separated and showed satisfactory catalytic activity after five reuse cycles. The current work has clearly demonstrated that the application of hydraulic cavitation technology to the solid‐acid‐catalysed epoxidation reaction of soybean oil can shorten the reaction time, increase the relative conversion to oxirane, and be a viable method with promising applications.

“…Tong et al 250 have reported the highest current density achievement of Ni‐Co base catalyst of urchin‐like structure Ni‐Co‐P‐O nanocomposite for methanol electro‐oxidation materials in alkaline medium of about 1567 A g −1 and have a good durability (≥20 000 second). The exploration of nickel‐based catalyst is blooming and gets more popular as many researchers start to work with various Ni‐based binary composite such as Ni/TiO 2 nanotubes, 251 Cu‐Ni/g‐C 3 N 4 nanosheets, 252 Ni(II)‐TiO 2 ‐SnO 2 /SO 4 2− , 253 amorphous Ni‐B‐Co nanoparticles, 254 and NiO‐CeO 2 nanosheets 255 .

Summary Direct liquid fuel cell (DLFC) is one of the leading fuel cell types due to their great features of superior energy density, modest configuration, small size in fuel container, immediate boosting, and effortless storage and carriage. Commercially used liquid fuel types are prepared using alcohols, such as methanol or ethanol, glycol, and acids. DLFCs face great challenges although they are potentially far‐reaching depending on the expensive catalysts and the use of high‐loading catalyst. More questions that should be addressed to ensure excellent DLFC performance include cathode flooding, fuel crossover, numerous side yield production, fuel security, and unverified elongated‐duration robustness. Further studies need to be carried out to ensure the continuous improvement of the quality of DLFCs' performance and their penetration in the commercial market. To date, direct liquid fuel cells made of methanol and ethanol have been successfully produced in commercial scale, but other types of DLFCs are still under study. In this review, introduction to DLFC will be discussed by covering work and commercialization as well as recent progress and challenges encountered.

Nowadays, the development and utilization of clean energy are becoming increasingly urgent. Among them, methanol is a new, clean, and efficient energy source. Therefore, more and more studies are focusing on methanol anodic oxidation (MOR). In this work, nanoflower and hollow spherical NiO was synthesized by a simply hydrothermal method and then modified by Co ion, NiS2 and carbon nanotubes (CNTs). The optimal Co/NiO(f)/NiS2−CNT exhibits flower‐like morphology with a larger specific surface area, enlarged electrochemically active surface area and higher conductivity, which improve the electron transfer ability and electrocatalytic activity compared with pure NiO(f), NiO(f)/NiS2, NiO(f)/NiS2−CNT and hollow spherical Co/NiO(hs)/NiS2−CNT. The current density is ultrahigh of 203.46 mA ⋅ cm−2 at 0.8 V, which is 36 times higher than pure NiO(f) and almost 2 times higher than Co/NiO(hs)/NiS2−CNT. Therefore, this work offers a highly efficient and stable NiO based catalyst for methanol oxidation reaction.
