Oxide perovskites, double perovskites and derivatives for electrocatalysis, photocatalysis, and photovoltaics

Abstract

Oxide perovskites and their derivatives are attractive candidates for the diverse applications in renewable energy conversions due to their unique structural and compositional flexibility and high material stability.

Electrochemically Induced Phase Changes in La2CuO4 During Cathodic Electrocatalysis

“…Materials based on the perovskite crystal structure have maintained significant attention as electrocatalysts due to their amenability to compositional tuning . Ruddlesden Popper oxides (RPOs) are a class of perovskites that contain alternating layers of electrically insulating rock salt (AO) and semiconducting perovskite (ABO 3 ) crystal structures.…”

Stochastic replica voting machine prediction of stable cubic and double perovskite materials and binary alloys

“…Our interest in Bi-based oxide double perovskites is motivated by the goal to achieve stable and non-toxic alternatives for lead-halide perovskites that have recently emerged as high-performance semiconductors with applications in solar cells and light-emitting diodes, but are plagued with instability and toxicity issues. [69][70][71] For the double perovskites, we define the octahedral and tolerance factors by Eqs. (14,15):…”

Bimodal Heterogeneous Functionality in Redox‐Active Conjugated Microporous Polymer toward Electrocatalytic Oxygen Reduction and Photocatalytic Hydrogen Evolution

“…A global increase in demand for energy and the rapid depletion of nonrenewable energy sources stem the quest for alternative energy sources. To this end, electrochemical and photochemical conversion of naturally abundant renewable resources (water and sunlight) into chemical energy are considered to have the potential to change the global energy landscape . In electrocatalysis, electrochemical redox reactions operate at a certain potential on the electrode surface.…”

“…To this end, electrochemical and photochemicalc onversion of naturally abundant renewable resources (watera nd sunlight) into chemical energy are considered to have the potential to change the global energy landscape. [1][2][3][4][5] In electrocatalysis, electrochemical redox reactions operate at ac ertain potential on the electrodes urface. This process has high significance for energyc onversion and storage systems such as fuel cells and in metal-airb attery applications.…”
