“…It is worth mentioning that amorphous TMBs are inevitably oxidized when exposed to air and water, thus forming oxides/hydroxides on the surface. 94,252,254,257 The presence of oxides/hydroxides can benefit the alkaline HER process. For instance, Chen et al…”

“…The introduction of a secondary metal/non-metal element can enhance the catalytic HER activity because of the regulated electronic structure and synergistic effect. 258 Hitherto, Co-Mo-B, 258,259 Co-Ni-B, 257,260 Co-W-B, 261 and Co-B-P 262 have shown decent catalytic properties towards HER in basic media. Apart from those aforementioned strategies mainly focus on enhancing the intrinsic catalytic activity of the catalysts, constructing porous nanostructures has also been proved to be an efficient strategy for enhancing the catalytic performance of the catalysts.…”

“…The interaction between Co and H is too strong in Co–P, but in Co–P–B, the bonding is optimized owing to the transfer of electrons from B to Co, thereby increasing HER activity. Apart from these elements, HER activity of many other ternary catalysts has been reported, but no efforts were taken to understand the role of incorporated metals.…”

“…It was observed that most of the Co–B nanoparticles were located on the surface of CNTs while some were encapsulated inside the tube. The electrochemical performance of the composite was evaluated for OER, establishing η 10 = 370 mV in 0.1 m KOH with a stability for 51 h.

“…The group of Zhang et al also synthesized Co–Ni–B and found that the molar ratio of Ni/(Ni + Co) = 10% yields the best performance for OER in 1 m KOH. Co–Ni–B supported on Ni foam, carbon cloth and rGO were reported by different groups in a bid to lower down the overpotential. For HER, Co–Ni–B/CC shows a lower overpotential of η 10 = 80 mV ( Figure a), which was also attributed to the formation of very small‐sized particles with average diameter of 5–10 nm (Figure b).…”

Electrocatalytic water-splitting has gained a firm hold in the area of renewable hydrogen production owing to its integrative compatibility with intermittent energy sources. However, wide-scale implementation of this technology demands discovery of new electrode materials that strike a good balance between efficiency, stability, and cost. In the pool of inexpensive electrodes capable of catalyzing hydrogen and oxygen evolution reactions, metal borides/ borates have made a big splash in the last decade. However, the research in this family of electrocatalysts remains unorganized owing to the diversity of reports. This review summarizes the past and present research progress in metal borides/borates for electrocatalytic water-splitting. The fundamental reasons for electrochemical behavior in different metal borides/borates are highlighted here, also including some comments regarding erroneous practices in the performance evaluation of metal borides/borates. Various strategies used to enhance the electrocatalytic performance of metal borides/borates are discussed in detail. Different methods evolved over the years for the synthesis of metal borides/ borates are also discussed. Finally, an assessment of the commercial viability of metal borides/borates is made and future research directions are suggested. multimetal oxides, [18,19] layered double hydroxides, [20] oxyhydroxides, [21] and perovskites. [13,18] In addition to these, there has been the family of transition-metal borides/borates that have garnered enormous interest in the recent past. Though transition-metal borides (TMBs) have been used for water electrolysis since many decades, they were not really seen as potential candidates to replace noble metal catalysts, until recently. Indeed, in 2009, the group of Daniel Nocera reported in situ formed Co [22] and Ni [23] borates as analogous catalysts to Co phosphate, [24] for near-neutral water-splitting. Later, the groups of Hu [25] and Patel [26] reported development of Mo boride and Co boride, respectively, for electrocatalytic water splitting. Following these reports, transition-metal borides/ borates [27][28][29][30][31][32] were developed using various techniques and were used extensively for water-splitting reactions, in different pH solutions. Here, we would like to inform the readers that usually boron-based catalysts that are developed in situ using electrodeposition are referred to as "borates" (denoted as M-B i , M = metal) while those catalysts prepared by any other technique are referred to as "borides" (denoted as M-B). Over the past 5-6 years, a lot of studies have been carried out on borides/borates with remarkable results, presenting new possibilities in search for non-noble electrocatalysts. The electrochemical performance, stability and other important properties of all the metal borides reported so far are enlisted in Table 1 while that of metal borates are listed in Table 2. However, there are a lot of aspects that are not yet understood completely about borides/borates. For instance, the o...

Electrochemical water splitting is a feasible method for producing environmental benignity energy of hydrogen, while high price and low availability on the earth of noble electrocatalysts constrain their global-scale application. Transition metal borides (TMBs) have displayed unique metalloid characteristic and outstanding performance for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) in the last few decades. Herein, recent developments of the TMBs for HER and OER are summarized. Initially, the impact factors and relevant evaluation of electrocatalytic performance are described, that is, overpotential, Tafel slope and exchange current density, stability, faradaic efficiency, turnover frequency, mass and specific activities. Moreover, the optimization strategies of borides are emphasized, which principally include coupling with effective substrates, elemental doping, phase modification, interfacial engineering, and morphology control. Finally, in order to reach the goal of application, the remaining challenges and perspectives are given to point out a direction for enhancing the performance of borides.
