While detailed studies have revealed the mechanisms involved in photocatalytic DRM at metal-semiconductor interfaces, less attention has been devoted to how high surface area semiconductor supports may enhance such conversions. Here we structure triblock terpolymer self-assembly directed sol-gel derived transition metal oxide (Ta2O5 or TiO2) supports of Rh-decorated photocatalysts into various equilibrium and non-equilibrium derived porous morphologies and show how they modulate single-pass conversion, total production rate, and material efficiency. Supported by in-depth materials characterization and flow simulations rationalizing observed trends, results reveal record catalyst performance. Our work suggests that asymmetric pore structures simultaneously optimizing mass transport and surface area may be well-suited to maximize photocatalyst performance.' description_type: abstract lang: eng ## Creator - name: William Moore role: author organization: Cornell University - name: Shusaku Shoji role: author orcid: https://orcid.org/0000-0002-8481-2633 organization: National Institute for Materials Science department: Research Center for Energy and Environmental Materials (GREEN)/Hydrogen Technology Materials Field/Hydrogen Production Catalyst Materials Group - name: Lieihn Tsaur role: author organization: Cornell University - name: Fei Yu role: author organization: Cornell University - name: R.
