“…Water splitting has sparked tremendous interest owing to its sustainable, simple, and high-efficiency merits to generate highpurity H 2 gas and alleviate growing environmental and energy issues [1][2][3][4][5][6]. Nevertheless, the sluggish kinetics in anodic oxygen evolution reaction (OER) [7,8] and cathodic hydrogen evolution reaction (HER) limits the energy conversion efficiency [9][10][11][12][13][14][15], which mainly depends on the catalytic performances of electrocatalysts [16][17][18][19][20][21]. At present, noble metal Pt-and Ru/Ir-based nanomaterials are the benchmark electrocatalysts toward HER and OER [22][23][24][25][26]; however, the high price and scarcity hinder the practical commercialization of water splitting technology [27][28][29][30].…”

The development of efficient electrocatalysts for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) with excellent catalytic performance and stability plays key roles in the commercialization of water splitting to generate hydrogen energy. Herein, a 2D-3D nanostructure composed of metal hydroxides and Prussian blue analogus (PBA) was in-situ decorated onto the NiFe foam (Pt-NiFe PBA) through a facile and scalable corrosive-coordinate approach. The specifically designed morphology favored the provision of abundant active sites, optimized the reaction pathway, and accelerated mass transport during the electrocatalytic process. Consequently, the as-synthesized Pt-NiFe PBA reached 10 mA cm −2 with small overpotentials of 29 and 210 mV in 1 mol L −1 KOH deionized water for HER and OER, respectively. Remarkably, Pt-NiFe PBA required an overpotential of 21 mV to drive 10 mA cm −2 in seawater containing 1 mol L −1 KOH with prominent durability. Moreover, with the as-synthesized Pt-NiFe PBA as bifunctional electrocatalyst, the Pt-NiFe PBA||Pt-NiFe PBA electrolyzer needed 1.46 and 1.48 V to drive 10 mA cm −2 in 1 mol L −1 KOH with deionized water and 1 mol L −1 KOH with seawater, respectively. Remarkably, sustainable energies were utilized to power the overall water splitting and stored as easily portable hydrogen energy.

“…In regard to water splitting, the involved hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) generate H 2 and O 2 , respectively. 167,168 For hydrogen-oxygen FCs, power can be produced through oxygen reduction reaction (ORR) and hydrogen oxidation reaction. However, the innate sluggish kinetics seriously restricts the properties of corresponding energy devices on account of multipleelectron transfer processes in electrocatalytic reactions.…”

The emerging use of laser irradiation in synthesis smartly bridges "nanotechnology" and "light", and has attracted enormous attention as an efficient synthetic methodology for versatile nanomaterials toward electrochemical energy storage and conversion devices (ESCDs). In this review, recent contributions and progress regarding the laser-induced nanomaterials for ESCDs are comprehensively summarized, with a special focus on their practical utilization in rechargeable batteries, supercapacitors and electrocatalysis. The laser-induced synthesis strategies and corresponding mechanisms involved in nanoarchitecture generation/regulation, including pulsed laser deposition and laser irradiation in liquid, are also discussed in detail. With the in-depth insights into the mechanisms and revolutionary advancements of laser irradiation technology, the comprehensive performances of ESCDs have been strikingly optimized. Finally, the existing challenges and future directions in this booming research field are outlined. This review will exert the significant guidance for future design and purposeful fabrication of advanced laser-induced nanomaterials with appealing properties for advanced ESCDs and beyond.

Silica Support Affects the Catalytic Hydrogen Evolution by Silver

Silica supported silver nanoparticles, SiO2‐Ag0‐NPs, catalyze the hydrolysis of BH4−. A comparison of the isotopic composition of the hydrogen formed in the hydrolysis of BD4− points out that the contribution of hydrides, the Heyrovsky mechanism, rather than that of hydrogen atoms, the Tafel mechanism, to the hydrogen evolution is considerably larger for the SiO2‐Ag0‐NPs catalyzed process than for the Ag0‐NPs catalyzed process. This indicates some electron transfer from the SiO2 to the silver that increases the negative charge on the Ag0‐NPs.
