Who we are
manuel p. soriaga
Dr. Soriaga’s research interests include: surface science of electrocatalysis; electrochemistry of nanostructured interfaces; electrode-surface coordination and organometallic chemistry; mixed-metal electrocatalysts for fuel cell applications; heterogenization of molecular catalysts; metal hydrides for hydrogen storage; surface redox capacity and cellular toxicity of nanoparticles, operando scanned-probe microscopy, differential electrochemical mass spectrometry; ex situ, in situ, and operandospectroscopy of electrode surfaces; and electrochemical surface science of heterogeneous reactions at the core of artificial photosynthesis.
In JCAP, Dr. Soriaga’s present research is focused on electrocatalytic reactions that underpin artificial photosynthesis; specifically, directed discovery of earth-abundant electrocatalysts, development of advanced surface-science methods for the characterization of benchmarked catalysts, and exploration of structure-composition-activity relationships to guide the expansion of catalyst-discovery strategies. The overall strategy seeks to gain basic understanding of the relationship between structure, composition, and reactivity; such knowledge is then implemented towards the synthesis of better catalysts.
