Abstract
This paper reports on the H2 gas sensing technique which has great importance in various practical applications. One of the current challenges lies in the H2 gas sensing technique is a high-temperature operation that increases explosion risk. To this objective, the room temperature chemochromic H2 sensing technique is an alternative, yet the development is not explored widely. We developed a novel quasi-reversible H2 sensing nanocomposite using an optimized ratio of Pd, WO3, and polyvinylpyrrolidone (PVP). It provides rapid eye-readable chemochromic response with a long recovery time for multiple repeated cycles, which has potential importance in industrial monitoring.
