Tags: Universiti Malaya, Malaysia, Science & Exploration, Energy & Environment
This research explores the improved photoelectrochemical performance of graphene nanoplatelet (GNP) electrodes catalyzed by tungsten nanoparticles and grown using hot-wire chemical vapor deposition at low substrate temperatures. The process results in large-area, multi-layer GNPs with enhanced electrical and structural properties, especially at 450°C. These GNP electrodes show better photocurrent density, charge transfer resistance, and donor density compared to tungsten carbide thin films. Applications include energy devices such as supercapacitors, batteries, and hydrogen production through water-splitting. The technology optimizes graphene growth for improved energy efficiency.
