Photochemistry and photocatalysi s often strugglewith activity and stability\, but offer exciting opportuni ties for selectivitycontrol.  While some photocatalysts showed efficient and/or selective chemicalconversion\, due to their excessively high bandga ps and hole-oxidation drivingforce\, the desirable photocatalysts\, promis ing for wide-ranging small-moleculeredox chemistry\, shall consist of one light-absorbing catalyst of tunablebandgaps\, with one coating overlayer i f needed for stable interfacial chemistry. Wewill discuss exciting opport unities in both energy conversion and selectivecatalysis by coupling photo - and thermo-catalysis at semiconductor surfaces.First\, we will discuss a decade of work on coatings\, which has drasticallyimproved semiconductor stability from a few minutes to one year of outdooroperation while effecti vely separating photo-generated electrons and holes atthe nanoscale. By pr obing and understanding dynamic semiconductor/liquid interfaces\,we co-des igned photocatalysts and reactors in a reactive flow to demonstraterecord efficiencies in water splitting and CO2 utilization. Thesemotivate new inq uiries into selective photo-thermal catalysis in vapor phases andorganic s olvents at elevated temperatures. Examples of photo-thermal CO2hydrogenati on\, especially those exothermic reactions that shift the equilibriumbackw ard\, will be discussed.              Bio:Shu Hu received his Ph.D. (2012) fromStanford University\, advised by Materials Scientist Pau l McIntyre andElectrochemist Chris Chidsey. Then\, he did postdoctoral wor k at Caltech withProfessor Nathan S. Lewis and Harry Atwater. He became th e faculty member atYale in 2016.  At Yale\, Prof. Hu’s lab re-discovere d a host of interfacialoxides and nitrides making possible the recent crit ical and successfuldemonstrations of semiconductor-based solar fuel device s. Hu leads an activegroup exploring the foundational science\, which inte rsects energy conversionand brain-inspired computing.  For these contribu tions\, he received some recognizable Awards&\; Honors: including DOE E arly Career Award (2021)\, Global Chinese ChemicalEngineer Award (2022)\, the ACS Energy &\; Fuel Emerging Researcher Award(2024)\,  and several lectureships\,including the Walter-Schottky Lecture.​ References:R.
