Regulating the electronic structure of the metal electrocatalyst is fundamental for its performance optimizing. The electronic states of the active metal centers are highly dependent on their coordination environment, especially when bonding is formed. The π back-bonding can induce great electron density redistribution around metals, yet it is barely applied in electrocatalyst design. Herein we electrodeposited metallic cobalt on black phosphorus(BP)nanosheets, forming BP-Co with a unique π back-bonding on the interfaces. The BP-Co exhibited high electrocatalytic activity and stability for hydrogen evolution reaction in alkaline electrolyte. The electrochemical and spectroscopic characterizations demonstrated that the BP acted as σ donor and π acceptor to coordinate with electron-rich metallic Co, similar to the phosphine complex. The directional σ bond strengthen the relationship between BP and Co, while the non-directional π bond accelerated the in-plane electron transfer. The π back donation also decreased the oxophilicity of Co to make BP-Co resist the poison from oxygen species. This study can intrigue new thinking prospective for the electrocatalyst design.

The radio-frequency (RF) performance of the p-type NiO-pocket based β-Ga_(2)O_(3)/black phosphorous heterostructureMOSFET has been evaluated. The key figure of merits (FOMs) for device performance evaluation include the transconductance(gm) gate dependent intrinsic-capacitances (Cgd and Cgs), cutoff frequency (fT), gain bandwidth (GBW) product and output-conductance(gd). Similarly, power-gain (Gp), power added efficiency (PAE), and output power (POUT) are also investigated for largesignalcontinuous-wave (CW) RF performance evaluation. The motive behind the study is to improve the β-Ga_(2)O_(3) MOS deviceperformance along with a reduction in power losses and device associated leakages. To show the applicability of the designeddevice in RF applications, its RF FOMs are analyzed. With the outline characteristics of the ultrathin black phosphorous layer belowthe β-Ga_(2)O_(3) channel region, the proposed device results in 1.09 times improvement in fT, with 0.7 times lower Cgs, and 3.27dB improved GP in comparison to the NiO-GO MOSFET. The results indicate that the designed NiO-GO/BP MOSFET has betterRF performance with improved power gain and low leakages.
