Adam has co-authored 300 peer-reviewed publications on catalysis, materials and surface science (h=index 76, 21289 cites) and his current research focuses on biomass valorisation and CO2 utilisation.

Abstract

Global acceptance of the anthropogenic origin of climate change from combustible carbon is driving the quest for new routes to sustainable energy sources [1]. Catalysis has a rich history of facilitating energy efficient, selective molecular transformations [2], and will play a pivotal role in overcoming the scientific and engineering barriers to sustainable and economically viable energy vectors. Here I outline challenges in the design of catalytic technologies for the upgrading of biomass to liquid transportation fuels, and of bio-derived molecules for fine chemical synthesis. Advances in the rational design of nanoporous solid acid and base catalysts enable the fabrication of hierarchical porous architectures [3] for energy efficient conversion of bio-oil components into biodiesel. Judicious compartmentalisation of different active sites within hierarchical porous frameworks (Figure 1) permits biodiesel production from low grade oils which cannot be processed by current technologies. Synergies between nanoporous solid acids and metal nanoparticles also facilitate active and selective upgrading of phenolic components of pyrolysis bio-oils to hydrocarbon fuels, and precious metal thrifting [4]. Active site compartmentalisation also facilitates chemical cascades to produce valuable chemical intermediates, exemplified by the stepwise production of cyanoesters [3].
