Hydrogen is positioned as a high value chemical with vast applications in the green energy transition.1-4 For this reason, the ability to produce hydrogen renewably is of significant interest.1-3 Solar driven photocatalytic water splitting is a promising technology in this regard as it would allow for clean hydrogen production using water, sunlight and a photocatalytic substrate.1-4 Traditional materials only absorb at most ~4% of energy we receive from the Sun, so efficient visible light sensitive materials are key.3 Heteroatom doping has been shown as a useful strategy in improving the visible light response of the most efficient photocatalysts.3,4 Traditional solid-state doping strategies result in inhomogeneity introducing defects and limiting activity.3 Herein is presented a synthetic approach to produce a homogeneously doped material with enhanced visible light absorbance.4 A metal-organic framework, or MOF, containing titanium and strontium is used as a crystalline inorganic template to house dopants prior to thermal conversion to yield a crystalline homogeneously doped metal oxide – SrTiO3:La/Rh – as shown through high resolution STEM-EDS mapping.4 Not only is the dopant distribution improved but superior control over dopant oxidation state is realized. This results in enhanced visible light absorbance and a reduction in bandgap to 2.45 eV from 2.70 eV as shown through Synchrotron XPS.3,4 As such, MOF derived materials show a proportionally greater visible light response than conventionally synthesized materials as well as evolving hydrogen deeper into the visible spectrum than previously observed.4 Synchrotron PD has revealed differences in crystal structure between MOF derived and conventional materials relating to dopant content, distribution and oxidation state that may explain differences in photocatalytic activity.4 Exploration of additional doping schemes has shown this approach to be generalizable across systems opening opportunities to explore previously unobtainable nanostructure assemblies.
