Abstract: The design and development of materials at the nanoscale has enabled efficient, cutting‐edge renewable energy storage, and conversion devices such as solar cells, water splitting, fuel cells, batteries, and supercapacitors. In addition to creating new materials, the ability to refine the structure and interface properties holds the key to achieving superior performance and durability of these devices. Atomic layer deposition (ALD) has become an important tool for nanofabrication as it allows the deposition of pin‐hole‐free films with atomic‐level thickness and composition control over high aspect ratio surfaces. ALD is successfully used to fabricate devices for renewable energy storage and conversion, for ex le, to deposit absorber materials, passivation layers, selective contacts, catalyst films, protection barriers, etc. In this review article, recent advances enabled by ALD in designing materials for high‐performance solar cells, catalytic energy conversion systems, batteries, and fuel cells, are summarized. The critical issues impeding the performance and durability of these devices are introduced and then the role of ALD in addressing them is discussed. Finally, the challenges in the implementation of ALD technique for nanofabrication on industrial scale are highlighted and a perspective on potential solutions is provided.

Abstract: Cerium doping into the V 2 O 5 lattice forms a reversible V 2 O 3 /VO redox pair after sequential methane partial oxidation and CO 2 /H 2 O splitting reactions and produces syngas (H 2 , CO) with fast rates and high oxygen exchange capacity.

Abstract: Reforming of methane to produce synthesis gas for the Fischer–Tropsch process provides an alternative to fossil fuels. Silica-encaged ceria–nickel hydroxide catalysts were produced by an in situ synthesis method to obtain ultrafine bimetallic species dispersed evenly within the mesoporous silica matrix. Dry reforming and reduction-oxidation cycling was undertaken with the materials. Catalysts with high content of nickel showed good activity during dry reforming, with conversions rates close to equilibrium in equimolar conditions. Insignificant deactivation of the catalysts was observed over 5 h and 50 h of reaction at 900 °C. Syngas production via reduction–oxidation cycling was shown to be insignificant as compared to continuous catalytic reforming.
