“…Since bubble evolution occurs at the triple‐phase boundary (Figure 19a), the detachment will be influenced by the displacement of the electrolyte at the solid−liquid interface, which is also known as wettability [314,334] . Generally, the contact angle ( θ ) is used to define surface wettability and it can be effectively modulated by adjusting the surface free energy and/or tuning the geometric structure of the catalyst [311–313] . For instance, Hao et al.…”

Hydrogen is a clean, flexible, powerful energy vector that can be leveraged as a promising alternative to fossil fuels. Additionally, green hydrogen production has been recognized as one of the most prevalent solutions to decarbonize the energy system. Water electrolysis studies have increased throughout the decade as higher industrial interest comes into play. The catalyst, system design, and configuration act in a congenial manner to deliver high‐performing water electrolysis. Despite performance targets peaking at high current densities, the current status of water electrolyzer technologies would require more research efforts to achieve such goals. This work presents a comprehensive review of how catalysts and electrolyzer designs can be enhanced to attain high current density water electrolysis. Modification strategies of catalysts, advances in characterization and modelling, and optimizing system designs are highlighted. Furthermore, this paper aims to elucidate the future research direction of water electrolysis to bridge the laboratory‐to‐industry gap.

Superhydrophobic surfaces (SHSs) exist in many biological organisms endowed by spectacular surface topographies, which provide important insights to drive a paradigm shift in design of engineering surfaces. Based on this, extensive progresses have been developed on bionic superhydrophobic strategies. Among them, SHSs based on topography of copper oxides exhibit considerable application prospects because of the steerability and diversity of topography, as well as additional performances, such as antibiosis, anticorrosion and catalysis. We first present a brief overview of the discovery of natural SHSs as well as fundamental understanding of surface wetting performance. Then, the structural effects in superhydrophobic systems based on the topographies of biological organisms and copper oxides are described. Finally, we highlight the perspectives on the novel design strategies of copper oxide-based SHSs that adapt to various practical applications.

“…There are several conventional fabrication techniques to synthesis ZnO nanorods such as thermal evaporation, chemical vapor deposition (CVD) and cyclic feeding CVD, sol-gel deposition, electrochemical deposition, hydrothermal and solvo-thermal growth, surfactant and capping agentsassisted [23,37,38] However, most of the synthesis methods are expansive, , complicated, nonscalable, environmentally hazardous and required well-trained and experienced operators [39][40][41] Therefore, it is crucial to have a simple fabrication method that can overcome most of the ZnO nanorods growth related issues. A simple hot water treatment (HWT) process has been recently demonstrated to produce metal oxide nanostructures on different metal surfaces [41].…”

Zinc-oxide (ZnO) nanostructures including nanorods are currently considered as a pioneer research of interest world-wide due to their excellent application potentials in various applied fields especially for the improvement of energy harvesting photovoltaic solar cells (PSC). We report on the growth and morphological properties of zinc-oxide (ZnO) nanorods grown on the surface of plain zinc (non-etched and chemically etched) plates by using a simple, economical, and environment-friendly technique. We apply hot water treatment (HWT) technique to grow the ZnO nanorods and varies the process parameters, such as temperature and the process time duration. The morphological, and elemental analysis confirm the agglomeration of multiple ZnO nanorods with its proper stoichiometry. The obtained nanostructures for different temperatures with different time duration showed the variation in uniformity, density, thickness and nanonorods size. The ZnO nanorods produced on the etched zinc surface were found thicker and uniform as compared to those grown on the non-etched zinc surface. This chemically etched Zinc plates preparation can be an easy solution to grow ZnO nanorods with high density and uniformity suitable for PSC applications such as to enhance the energy conversion efficiency of the photovoltaic (PV) solar cells towards the future sustainable green earth.
