“…By separating and directing them to the surface of catalysts, light illumination‐induced hot charge carriers can be coupled to various chemical/electrochemical reactions and accelerate the reaction rates. [ 181–183 ] In addition, sunlight is an environmentally friendly and inexhaustible resource in nature. Therefore, harvesting optical energy by grafting photosensitive materials onto catalysts represents a promising route to promote electrocatalytic HER/OER activity.…”

promising alternative to fossil fuels. Water electrolysis by renewable resourcederived electricity represents a facile and green route to produce H 2. [1-13] Generally, the key to implement high-performance water splitting is to develop economically viable, efficient, and robust electrocatalysts to lower the activation potential barriers. Thus far, researchers have devoted extensive enthusiasm to the investigation of electrocatalysts. Currently, most efforts have been taken on the search for new materials, [14-16] regulation of morphology, [17] crystallinity, [18] facet, [19] component, [20-24] defect, [25,26] matter phase, [27,28] or the compositing of various materials with synergy. [29-36] However, the performances of emerging nonnoble electrocatalysts still lag behind those of noble ones. To address this issue, researchers have turned their attention beyond the electrocatalysts themselves. Field-assisted electrocatalysis is the electrocatalytic reaction proceeded in the presence of a field. It represents a promising methodology since it exerts an additional degree of freedom to engineer an electrochemical process. Inspiringly, indisputable improvements in electrocatalytic hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) have been implemented with the assist of various fields, including electric field, magnetic field, strain, and light. For example, the electrocatalytic HER of a MoS 2 nanosheet is markedly boosted by simply exploiting a back gate voltage of 5 V. [37] Its overpotential at −100 mA cm −2 is decreased from 240 to 38 mV. In addition, enhancement of alkaline water electrolysis is achieved by applying a moderate magnetic field (≤450 mT) to an electrocatalytic anode consists of highly magnetic electrocatalysts. [38] Its current density increments are beyond 100%. Furthermore, the HER activity of β-PdH x increases monotonically as the applied strain increases from 0% to 4.5%. [39] Lastly, an approximately threefold increase in current density of Au-MoS 2 for electrocatalytic HER is realized upon the illumination of IR light. [40] These results undoubtedly elucidate that applying a field during electrocataly sis opens up great opportunities toward further improving electrocatalytic activity. Moreover, this approach provides merits of facile, dynamical, continuous, reversible, and universal control. Despite fascinating achievements, these investigations are relatively scattered. The underneath mechanisms and principles Hydrogen fuel is considered as one of the most clean renewable resources, warranting it a primary alternative to fossil fuels for future energy supplies. Electrocatalytic water splitting is an eco-friendly technique for high-purity hydrogen production. However, the sluggish dynamics of its two halfreactions, hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), are tough challenges impeding the practical application of this technology. In these years, external field-assisted HER and OER have attracted extensive research interests. Herein, the effects o...

Great effort has recently been made to develop noble‐metal nanomaterials with good activity, high durability, and appropriate selectivity to improve their efficiency in functional applications, while maintaining low cost. The use of noble metals not only makes the last requirement hard to meet but also restricts stability at high temperatures and limits mass production. Recently, some promising strategies, such as optimizing the components and fine‐tuning the structure, have been explored, which promise to enable the fabrication of unique noble‐metal nanostructures with lower loading and higher stability. Herein, recent achievements in manufacturing noble‐metal composites are reviewed, particularly focusing on unique and key factors in rational design and control of structure and components. Two applications of noble‐metal composites in optical and catalytic applications are focused on to illustrate their rational synthesis and design. In addition, current challenges and prospects for future development in this rapidly blossoming field are discussed.

“…Some researchers revealed that the hot holes act as strong oxidants to drive the electrons transfer from adsorbed molecules to the plasmonic nanoparticles. [170,171] Some works demonstrated that the plasmonic effects can lead to surface charge heterogeneity which results in decreasing d-band centre of Pt and thereby leads to inhibit the adsorption of poisoning species. [164,172,173] Therefore, profound and holistic investigations are still deeply required to precisely understand the mechanism or the contributions of each component, which can be extraordinarily helpful to develop high-efficiency AOR catalysts.…”
