This Viewpoint discusses the implications of the net zero energy transition on traditional chemical feedstocks and catalytic elements. While the full impact of the upcoming changes is difficult to assess, some trends from scenarios already underway can be mapped. For example, a steady growth in electric passenger vehicles will diminish transportation-related petroleum refining output, which could then create chemical feedstock gaps and changes in the supply/demand dynamics of certain critical metals. These impacts could present unexpected opportunities for emerging feedstocks such as biomass, sequestered CO2, and recycled carbon to bridge the supply gaps, even within the next decade. Further, catalytic metals such as Pd, Rh, and Pt will be displaced from petroleum refining and automotive exhaust catalytic converter applications and potentially become more available for producing chemicals and aviation fuels from emerging feedstocks. At the same time, metals such as Co and Ni, which are currently considered to be earth abundant, will face increasing demand in energy storage applications and thus could become less attractive for catalytic applications. The availability of carbon-free hydrogen and oxygen will facilitate the march toward decarbonization of the chemical industry. Finally, the enormity of displaced petroleum refining assets offers the possibility of repurposing some of them to process emerging feedstocks. These disruptions will have profound implications in future catalysis research and must be considered for a well-guided transition toward industrial sustainability.

“…21 Furthermore, the rich composition of termination groups on MXenes provides sufficient adsorption sites for active centers. 22 For instance, previous theoretical study has explored the catalytic performance of Cu tetramers on O-terminated Ti 2 C, in which the activity is promoted due to enhanced CO 2 adsorption on the Cu 4 /Ti 2 CO 2 catalysts. 23 Furthermore, reducing the size of active sites can also effectively improve the catalytic performance and atomic usage.…”

Developing efficient catalysts for the capture and direct conversion of CO 2 into various chemicals is essential to alleviate CO 2 emissions and minimize the negative environmental effects of fossil fuels. Combining density functional theory calculations and microkinetic analysis, we propose that single Bi atoms supported on V 2 CO 2 MXenes (Bi@V 2 CO 2 ) are promising single-atom catalysts (SAC) for CO 2 hydrogenation. The catalytic performance of Bi SACs is ensured by the stable single-atom dispersion of Bi atoms on V 2 CO 2 and enhanced adsorption of CO 2 . Of importance, Bi@V 2 CO 2 exhibits remarkable selectivity toward the synthesis of formic acid (HCOOH), in which the main competing reaction, namely, the reverse water gas shift (RWGS) and the formation of CO, is strictly prohibited. In contrast to conventional Cu or In 2 O 3 catalysts, CO 2 hydrogenation exhibits a unique mechanism on Bi@V 2 CO 2 , in which the formic acid is directly generated via a concerted pathway. As a result, the formation of both intermediate HCOO and COOH is prevented, leading to high selectivity (nearly 100%) toward HCOOH on Bi@V 2 CO 2 . Moreover, analysis of the kinetic behavior suggests that the stabilization of HCOOH adsorption would be an effective approach to promote catalyst performance toward methanol synthesis.

“…The catalytic efficacy is notably contingent upon the thermodynamic and mechanical robustness of 2D MXenes. 19 In the manufacture and application of nanosensors, stable mechanical performance of the component 2D films is crucial for the production and reusability of these devices. 20 However, even though the mechanical property of 2D COFs is a fundamental intrinsic feature relevant to most of their applications, there are relatively few reports on their mechanical behaviors.…”
