It is substantially challenging for non‐centrosymmetric (NCS) Hg‐based chalcogenides for infrared nonlinear optical (IR‐NLO) applications to realize wide band gap (Eg > 3.0 eV) and sufficient phase‐matching (PM) second‐harmonic‐generation intensity (deff > 1.0 × benchmark AgGaS2) simultaneously due to the inherent incompatibility. To address this issue, this work presents a diagonal synergetic...
Sodium‐ion batteries are a promising substitute for lithium batteries due to the abundant resources and low cost of sodium. Herein, honeycomb‐shaped MoSe2/reduced graphene oxide (rGO) composite materials are synthesized from graphene oxide (GO) and MoSe2 through a one‐step solvothermal process. Experiments show that the 3D honeycomb structure provides excellent electrolyte penetration while alleviating...
Inorganic chalcogenides have been studied as the most promising infrared (IR) nonlinear optical (NLO) candidates for the past decades. However, it is proven difficult to discover high‐performance materials that combine the often‐incompatible properties of large energy gap (Eg) and strong second harmonic generation (SHG) response (deff), especially for rare‐earth chalcogenides. Herein, centrosymmetric...
Controllable synthesis of ultrathin metal–organic framework (MOF) nanosheets and rational design of their nano/microstructures in favor of electrochemical catalysis is critical for their renewable energy applications. Herein, an in situ growth method is proposed to prepare the ultrathin NiFe MOF nanosheets with a thickness of 1.5 nm, which are vertically inlaid into a 3D ordered macroporous structure...
