Author is Rohloff, Martin; Anke, Bjoern; Kasian, Olga; Zhang, Siyuan; Lerch, Martin; Scheu, Christina; Fischer, Anna.

Anion substitution is an emerging strategy to enhance the photoelectrochem. performance of metal oxide photoelectrodes. In the present work, the effect is investigated of fluorine incorporation on the photoelectrochem. water oxidation performance of BiVO4 and Mo:BiVO4 thin film photoanodes. The BiVO4 and Mo:BiVO4 thin film photoanodes were prepared by a straightforward organometallic solution route involving dip coating and subsequent calcination in air. Fluorine modification was realized by applying a soft and low-cost solid-vapor reaction route involving fluorine-containing polymers and an inert gas atm. leading to novel F:BiVO4 and F/Mo:BiVO4 thin film photoanodes with substantially increased photoelectrochem. water oxidation properties. Deposition of the cobalt phosphate (CoPi) water oxidation catalyst allowed further enhancement of the photoelectrochem. performance. While Mo doping mainly improves light-harvesting, charge transport, and charge separation efficiencies, F modification was demonstrated to primarily affect the charge transfer efficiency at the semiconductor-electrolyte interface, thereby leading to a photocurrent increase of 40 and 21% upon fluorination of the BiVO4 and Mo:BiVO4 photoanodes, resp., and an applied bias photon-to-current efficiency increase of 35 and 5%, resp. It is demonstrated that cation and anion co-doping in BiVO4 as demonstrated for Mo and F allows combining the photoelectrochem. relevant benefits associated with each type of dopant.

Author is Baumgartner, Lorenz M.; Coley, Connor W.; Reizman, Brandon J.; Gao, Kevin W.; Jensen, Klavs F..

A mixed-integer nonlinear program (MINLP) algorithm to optimize catalyst turnover number (TON) and product yield by simultaneously modulating discrete variables-catalyst types-and continuous variables-temperature, residence time, and catalyst loading-was implemented and validated. Several simulated case studies, with and without random measurement error, demonstrate the algorithm’s robustness in finding optimal conditions in the presence of side reactions and other complicating nonlinearities. This algorithm was applied to the real-time optimization of a Suzuki-Miyaura cross-coupling reaction in an automated microfluidic reaction platform comprising a liquid handler, an oscillatory flow reactor, and an online LC/MS. The algorithm, based on a combination of branch and bound and adaptive response surface methods, identified exptl. conditions that maximize TON subject to a yield constraint from a pool of eight catalyst candidates in just 60 experiments, considerably fewer than a previous version of the algorithm.
