Enhancing Nitrogen Reduction Reaction through Formation of 2/2D Hybrid Heterostructures of MoS@rGO.

Given the challenging task of constructing an efficient nitrogen reduction reaction (NRR) electrocatalyst with enhanced ambient condition performance, properties such as high specific surface area, fast electron transfer, and design of the catalyst surface constitute a group of key factors to be taken into consideration to guarantee outstanding catalytic performance and durability. Thereof, this work investigates the contribution of the 2D/2D heterojunction interface between MoS and reduced graphene oxide (rGO) on the electrocatalytic synthesis of NH in an alkaline media. The results revealed remarkable NRR performance on the MoS@rGO 2/2D hybrid electrocatalyst, characterized by a high NRR sensitivity (faradaic efficiency) of 34.

Global irrigation contribution to wheat and maize yield.

Irrigation is the largest sector of human water use and an important option for increasing crop production and reducing drought impacts. However, the potential for irrigation to contribute to global crop yields remains uncertain. Here, we quantify this contribution for wheat and maize at global scale by developing a Bayesian framework integrating empirical estimates and gridded global crop models on new maps of the relative difference between attainable rainfed and irrigated yield (ΔY).
