“…The intentional modification of the copper surface chemistry plays a crucial role in adjusting the binding affinity of the reaction intermediates, which, in turn, has a substantial impact on the overall efficiency of CO 2 ER. There is still much room for the catalyst design and synthesis of high-performance and cost-effective CO 2 ER electrocatalysts. , Therefore, numerous heterogeneous catalyst formulations in the form of powder and thin films have been researched to enhance the CO 2 electrocatalytic reduction activity. ,, A simplified product distribution diagram of CO 2 ER provides insight into the expected product outcomes during the electrochemical reduction of carbon dioxide (Figure (b)) …”

The electroreduction of carbon dioxide (CO 2 ) using copper-based catalysts presents an effective strategy for reducing greenhouse gas emissions while generating lucrative chemical feedstocks. Copper (Cu) has emerged as one of the most efficient catalysts for CO 2 electroreduction (CO 2 ER) due to its abundant availability, high selectivity, and low cost. The most extensively researched copper-based catalysts for CO 2 ER always depend heavily on the valence states of copper. However, the performance of Cu catalysts can also vary significantly depending on their crystallographic facets. In recent years, considerable attention has been directed toward understanding the role of crystal facets in copper-based catalysts and their impact on the electrocatalytic performance for CO 2 ER. This review article aims to provide a comprehensive and state of the art overview of the literature on copper-based catalysts for the electroreduction of CO 2 with more emphasis on the facet-dependent thin films. The primary focus is on the most recent advancements in facet-dependent copper-based catalysts in the context of CO 2 electroreduction, with an emphasis on enhancing selectivity for C2 products using thin film electrocatalyst. Along with this, a brief mention of the mechanistic investigations is also included. Finally, a brief perspective in this research direction is provided in addition.

A novel H 2 sensor using tapered optical fiber coated with Pd/ZnO nanostructures have been developed. The ZnO nanostructures was synthesized and deposited onto tapered optical fiber via chemical bath deposition (CBD) method. The ZnO was characterized by FESEM, XRD and EDX to confirm the material properties. It was discovered that the sensor is sensitive towards different concentrations of H 2 in synthetic air at 180° C of operating temperature. By varying the deposition time of ZnO coating, different thickness of ZnO layer can be obtained. It was observed that with 280 nm thickness, the maximum absorbance response can be achieved. Further investigation with sensor sample of as-prepared and annealed was carried out to study its sensing performance towards H 2 . The absorbance response of 280 nm thickness of annealed Pd/ZnO has increased 64% as compared to as-prepared Pd/ZnO upon 1% H 2 exposure in the synthetic air when measured in the visible to near infra-red optical wavelength. It can be concluded that the Pd/ZnO optical fiber sensor with thickness around 280 nm provided better sensitivity in sensing H 2 at 180°C as compared to other thicknesses investigated.
