✦ Synopsis

Hydrogen reduction of V z 0 5 and WO3 catalysed by rhodium, both in the pure form and supported on kieselguhr, has been studied. The products obtained at 300 'C have been identified as VOZ and HzW03. In situ electrical resistivity measurements on VzO5 pellets, both pure and admixed with the catalyst, show an anomalous resistance increase with temperature, perhaps arising from chemisorption and spillover of hydrogen from rhodium.
