Atomic carbon plays a role in steering selectivity in electrochemical carbon mono-/dioxide reduction. Appropriate binding strengths of CO and C, combined with four-fold sites, constitute fundamental features toward selective multicarbon production.

Key Aspects

Electrochemical reduction of carbon-dioxide/carbon-monoxide (CO<sub>(2)</sub>R) to fuels and chemicals presents an attractive approach for sustainable chemical synthesis, but also poses a serious challenge in catalysis. Understanding the key aspects that guide CO<sub>(2)</sub>R towards value-added multicarbon (C<sub>2+</sub>) products is imperative in designing an efficient catalyst. Herein, we identify the critical steps toward C<sub>2</sub> products on copper through a combination of energetics from density functional theory and micro-kinetic modeling. We elucidate the importance of atomic carbon in directing C<sub>2+</sub> selectivity and how it introduces surface structural sensitivity on copper catalysts. This insight enables us to propose two simple thermodynamic descriptors that effectively describe C<sub>2+</sub> selectivity on metal catalysts beyond copper and hence it identifies an intelligible protocol to screen for materials that selectively catalyze CO<sub>(2)</sub> to C<sub>2+</sub> products.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.
