Hydrogen gas has been regarded as an ideal energy source that could replace the need of fossil fuels, based on its high energy density with zero carbon emissions. The production of hydrogen via electrolysis of water is not a new field, but the technology has seen significant advancements in recent times, owing to the proportional growing demand of clean and affordable energy. This review discusses the most recent progresses achieved in the area of earth abundant catalysis, particularly, non‐precious metal (Ni, Co, Fe, Mo, W)‐based catalysts that are being utilized for the electrochemical hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in alkaline solutions. Based on the type of materials, the discussions are categorized into sections attributed to transition metal alloys, hydroxides, oxides, chalcogenides, carbides and nitrogenous materials. In general, a brief introduction of HER and OER mechanisms followed by a detailed discussion of the presently considered catalysts with endeavors have been made to highlight the new technologies and alternative approaches that are being considered promising towards production of clean H2 energy. Finally, a prospective has been provided to accentuate the future of non‐noble metal based catalyst in electro‐catalytic water splitting reactions.

“…In the past decades, great efforts have been made to develop non-Pt family metals or even metal-free alternatives as ORR catalysts [1,2]. Especially, rapid progress has been achieved on metal-free ORR electrocatalysts, such as mesoporous carbons, heteroatom-doped graphene, and carbon nanotubes (CNTs) [3][4][5][6][7][8][9][10]. Very recently, studies on electrocatalysis of transition metal carbides (MXenes) have attracted increasing attention [11][12][13][14][15][16][17].…”

MXenes, a new family of multifunctional two dimensional (2D) solid crystals integrating high electroconductivity and rich surface chemistries, are promising candidates for electrolysis, which, however, have rarely been reported. Herein, free-standing ultrathin 2D MXene nanosheets were successfully fabricated from bulky and rigid MAX phase ceramics by liquid exfoliation with HF etching (delamination) and TPAOH intercalation (disintegration). The high oxygen reduction reaction (ORR) performance has been obtained, due to the extremely small thickness of the asfabricated Ti 3 C 2 around 0.5-2.0 nm, equivalent to the dimensions of single-layer or double-layer Ti 3 C 2 nanosheets in thickness. The ORR performance of the obtained Ti 3 C 2 MXene-based catalyst exhibits desirable activity and stability in alkaline media. This study demonstrates the potential of earth-abundant 2D MXenes for constructing high-performance and cost-effective electrocatalysts.

“…Inorganic functional materials are becoming more and more important due to the diversity of structures and their wide range of applications [1][2][3][4][5][6][7][8][9]. In the recent years, borate attracts more attention owing to the ability of the B atoms that can form the BO 3 triangles or the BO 4 tetrahedra.…”

Two borate-carbonates Ba 4 M(CO 3) 2 (BO 3) 2 (M = Ba, Sr) have been successfully synthesized in the open air representing the first examples of borate-carbnate complex. Their structures were determined by single crystal X-ray diffraction and they both crystallize in same space group, Pnma. Their structures feature a Ba/Sr-based three dimensional framework composed of the BaO 8 polyhedra (the SrO 8 polyhedra), isolated BO 3 and CO 3 triangles. Detailed structure analysis shows that the intergrowth of [Ba 3 (BO 3) 2 ]/ [Ba 2 Sr(BO 3) 2 ] and [BaCO 3 ] layers favors the formation of these two borate-carbonates. In addition, their syntheses, spectroscopic properties and thermal behaviors were investigated.
