Project CIPHER has recently published an article titled “Templated synthesis of transition metal phosphide electrocatalysts for oxygen and hydrogen evolution reactions” . The publication was a collaboration among research fellows— Rose Anne Acedera, Alicia Theresse Dumlao, Dr. Maricor Divinagracia-Luzadas, and Dr. DJ Donn Matienzo, and project staff —Prof. Joey Ocon, Asst. Prof. Julie Anne Paraggua, and Prof. Po-Ya Abel Chuang. The review article was published in Elsevier’s Journal of Energy Chemistry on November 8, 2023. In this review, different synthesis techniques resulting in specialized morphologies of transition metal phosphide (TMP) material catalysts for water electrolysis were discussed, detailing the methodologies followed and the resulting catalyst’s structure, morphology, and electrochemical performance for OER and HER. A comparison of these templated synthesis methods was also presented by explaining each template's different advantages and limitations. Perspectives on the design, synthesis, and evaluation through materials characterization, theoretical calculations, and electrochemical activity and stability of hollow and porous OER and HER catalysts were also suggested. Specifically, the use of hydrogen bubbles as a template was recommended to simplify synthesis while still prioritizing catalyst activity and stability.
