Nanocatalysts have emerged as promising candidates for enhancing the performance of Direct Liquid Fuel Cells (DLFCs). These fuel cells directly convert the chemical energy stored in liquid fuels into electrical energy. Nanocatalysts, characterized by their nanoscale size and high surface area, offer unique advantages for catalytic reactions in DLFCs. This review provides an overview of the role and potential of nanocatalysts in DLFCs. Nanocatalysts are often combined with suitable support materials like carbon aerogels or metal oxides to enhance conductivity and stability. The utilization of nanocatalysts in DLFCs offers several benefits. The enhanced catalytic activity and improved reaction kinetics contribute to higher power output and fuel utilization efficiency. Nanocatalysts also broaden the range of liquid fuels that can be used, thereby increasing the versatility of DLFCs. The goal of improving catalyst efficiency has been the focus of contemporary research. DLFCs utilize nanocatalysts, which are tiny metal particles supported by metal oxides or nanocarbons like ruthenium and platinum. This study explores into their structure, support networks, and synthesis challenges, providing a comprehensive exploration of nanocatalyst advancements in DLFCs. Improving DLFC performance and efficiency involves investigating these nanocatalysts. By tackling current challenges, nanocatalysts hold the promise to transform DLFCs and play a pivotal role in advancing clean energy conversion technologies. [ABSTRACT FROM AUTHOR]

This review discusses the impact of alpha‐gallium oxide (α‐Ga2O3) on potential high‐power device applications. To date, there are high requirements for efficient high‐power delivery and low‐power loss device material in power industries. III‐VI oxide semiconductor family, α‐Ga2O3, is recognized as a promising, future power semiconductor material owing to its ultrawide bandgap of 5.3 eV, high breakdown field of 10 MV cm−1, and a large Baliga's figure of merit. A highly expected α‐Ga2O3 power semiconductor electronic device (Schottky barrier diode and field effect transistor) can perform better than conventional semiconductor materials Si, SiC, and GaN. However, there is a lack of research into using mist CVD to cultivate high‐quality α‐Ga2O3 for high‐power devices like FETs and SBDs. Currently, the mist CVD‐grown α‐Ga2O3 thin film power device is still in its early stages, and one of the main reasons for this is defects of the thin film, which impede material electron mobility. The purpose of writing this article is to provide an overview of the development of α‐Ga2O3 heteroepitaxial thin film by the mist CVD process for use in high‐power devices such as Schottky barrier diodes (SBD) and field effect transistors (MOSFET). 1. α‐Ga2O3 α‐Ga2O3. Furthermore, multiple viewpoints highlight the challenges and future trends toward device performance sustainability in a scientific society. [ABSTRACT FROM AUTHOR]

Summary: Ionic liquids (ILs) are promising solvents for catalytic and electrolyte applications, gas absorption, and extractions in electrochemical systems due to their useful features, such as high conductivity and good thermal, chemical, and electrical stability. This review focuses on incorporating ILs into fuel cell (FC) systems, specifically into two main components of FC (ie, polymer electrolyte membrane and electrocatalyst). In FC, a polymer electrolyte membrane with excellent conductivity and deprived of humidity even at high temperatures must be created for effective early commercialization of this technology. Electrocatalyst performance can also be enhanced with additive materials, such as ILs, thus further improving the entire achievement of FCs. This work discusses the most important reasons for ongoing studies and outlines the current progress in using ILs as a revolutionary form of polymer electrolyte membrane and electrocatalyst.
