“…These activities are also associated with effective active sites that can be found from the double layer capacitance (C dl ). 60 C dl values have been found to be 0.53 and 0.61 mF for BaMoO 4 and BaWO 4 , respectively, which show that BaWO 4 has more catalytically active sites for the HER due to increasing charge accumulation on the piezocatalysts for redox reactions. 26 Piezo/photopiezocatalytic HER mechanism Based on the experimental results, a possible mechanism for piezocatalytic hydrogen production is proposed in Fig.…”

“…This observation can be explained by the WO 3 nanostructured surface acting as an electron transfer layer in the WO 3 NLs‐ITO electrode, thereby reducing charge‐transfer resistance (R ct ) [54] . R ct is a measure of the interfacial kinetics of catalysts, where low R ct values are indicative of a fast reaction rate [55] . Additionally, R ct was also calculated from the equivalent circuit as shown in the inset of Figure 4b.…”

We report the development of a multifunctional, nanostructured tungsten oxide catalytic device using block copolymer (BCP) templating, which was utilised for both the oxygen evolution reaction (OER) and epinephrine (EP) detection. The device was constructed by depositing a self-assembled BCP film atop an indium tin oxide (ITO) substrate. A tungsten precursor was then selectively coordinated into the film via liquid phase infiltration, which upon UV-ozone treatment yielded WO 3 surface nanolines (NLs) with excellent surface coverage. The resulting device was firstly investigated as a photoanode for OER. The onset overpotential of the WO 3 NLs-ITO electrode was determined to be 240 mV and 390 mV, with and without light illumination, respectively. Moreover, the applicability of the WO 3 NLs-ITO device for the electrochemical sensing of EP was explored using cyclic voltammetry and amperometry, exhibiting a linear response in a wide working range of 0.5-250 μM with a sensitivity of 0.0491 μA μM À 1 and detection limit of 0.086 μM. The device demonstrated high durability over multiple EP measurements, as well as strong anti-interference abilities versus well-known interfering compounds. Additionally, the device was successfully applied to accurately determine EP concentrations in commercial drug samples. The results of this study attest to the significant potential of BCP templating for developing low cost, high-performance electrocatalytic devices for future nanomanufacturing strategies.

“…prepared amorphous nickel thio‐selenide which was used for urea‐assisted alkaline HER in 1 m KOH + 0.5 m urea. [ 59 ] The nickel thio‐selenide showed largest adsorption energy value (0.97 eV) among NiS (−0.54 eV) and NiSe (−0.50 eV), as shown in Figure 7a,b. The NiSSe electrode showed both high hydrophilicity and oxygen repellency, which contributed to the affinity between the electrolyte and the electrode.…”

Environmentally friendly energy sources (e.g., hydrogen) require an urgent development targeting to address the problem of energy scarcity. Electrocatalytic water splitting is being explored as a convenient catalytic reaction in this context, and promising amorphous nanomaterials (ANMs) are receiving increasing attention due to their excellent catalytic properties.Oxygen group‐based amorphous nanomaterials (O‐ANMs) are an important component of the broad family of ANMs due to their unique amorphous structure, large number of defects, and abundant randomly oriented bonds, O‐ANMs induce the generation of a larger number of active sites, which favors a better catalytic activity. Meanwhile, amorphous materials can disrupt the inherent features of conventional crystalline materials regarding electron transfer paths, resulting in higher flexibility. O‐ANMs mainly include VIA elements such as oxygen, sulfur, selenium, tellurium, and other transition metals, most of which are reported to be free of noble metals and have comparable performance to commercial catalysts Pt/C or IrO2 and RuO2 in electrocatalysis. This review covers the features and reaction mechanism of O‐ANMs, the synthesis strategies to prepare O‐ANMs, as well as the application of O‐ANMs in electrocatalytic water splitting. Last, the challenges and prospective remarks for future development in O‐ANMs for electrocatalytic water splitting are concluded.
