Defective two-dimensional layered heterometallic phosphonates as highly efficient oxygen evolution electrocatalysts

Abstract

High-performance nonprecious electrocatalysts toward water splitting are highly demanded but currently it is still challenging. Here, we demonstrate that heterometallic two-dimensional (2D) metal phosphonates with improved catalytic activity and durability...

Electronic structure modification of ultrathin MnFeOOH and integration with Ni3S2 as bifunctional electrocatalysts for improved alkaline water splitting

“…After years of development, many transition metal electrocatalysts, such as transition metal oxides, hydroxides, sulfides, carbides, sulfides and MOFs, etc., have made significant progress. [6][7][8][9][10][11][12][13] However, these catalysts still generally have poor conductivity, and unsatisfactory catalytic activity and stability. 14 Additionally, most current electrocatalysts are single functional, while bifunctional water electrolysis catalysts are relatively rare.…”

Improving robustness in emotion recognition via adversarial training

“…With the proliferation of the internet and mobile devices, emotion speech recognition is increasingly applied in humancomputer interaction, intelligent assistants, and emotional analysis. However, this progress is accompanied by various adversarial attacks that can lead to model misjudgements, severely affecting user experience and system security [1][2][3].…”

Rational design of heterostructural heterometallic phosphonates as highly efficient electrocatalysts for overall water splitting under alkaline conditions

“…Compared with carboxylate based analogues, phosphonate based MOF materials exhibit superior stability. 31,32 Therefore, phosphonate based MOF materials have unique advantages in the field of catalytic water splitting. To improve the catalytic activity of MOF based catalysts, some effective strategies have been developed, including employment of conductive MOF materials (such as porphyrin-based MOFs), 33,34 heterometal doping, 35,36 reducing the particle size or layer, 37,38 defect engineering, 39 and so on.…”
