WebCatalysts do not change the equilibrium concentrations of reacting substances in reversible reactions. Instead, they increase the rate of reaction - often allowing a lower temperature to be used.... WebThe research that underpins industrial catalysis is equally ubiquitous. From a single PhD student to the might of an industrial R&D laboratory, all can contribute to the journey that takes a catalytic process from basic idea through to full plant realisation. In this special issue on ‘Homogeneous and heterogeneous catalysis in industry’ we ...
