Passive Radiant Cooling and Heating are green and sustainable methods of radiant heat management without consuming additional energy. However, the absorption of sunlight and poor insulation of materials can reduce radiative cooling and also affect radiative heating performance. Herein, we have constructed porous hierarchical dual-mode silk nanofibrous aerogel (SNF) films with high mechanical toughness and stability using silk nanofibers/GO.

The CsPbBr perovskite exhibits strong environmental stability under light, humidity, temperature, and oxygen conditions. However, in all-inorganic perovskite solar cells (PSCs), interface defects between the carbon electrode and CsPbBr limit the carrier separation and transfer rates. We used black phosphorus (BP) nanosheets as the hole transport layer (HTL) to construct an all-inorganic carbon-based CsPbBr perovskite (FTO/c-TiO/m-TiO/CsPbBr/BP/C) solar cell.

Conversion of solar energy into value-added chemicals through photoelectrochemistry (PEC) holds great potential for advancing sustainable development but limits by high onset potential which affects energy conversion efficiencies. Herein, we utilized a CuPd cocatalyst-modified Sb2(S,Se)3 photocathode (CuPd/TSSS) to achieve an ultra-low onset potential of 0.83 VRHE for photoelectrochemical ammonia synthesis.

The H-evolution kinetics play a pivotal role in governing the photocatalytic hydrogen-evolution process. However, achieving precise regulation of the H-adsorption and H-desorption equilibrium (H/H) still remains a great challenge. Herein, we propose a fine-tuning d-p hybridization strategy to precisely optimize the H/H kinetics in a Ni-B modified CdS photocatalyst (Ni-B/CdS).

Organic-inorganic hybrid perovskites have demonstrated great potential for flexible optoelectronic devices due to their superior optoelectronic properties and structural flexibility. However, mechanical deformation-induced cracks at the buried interface and delamination from the substrate severely constrain the optoelectronic performance and device lifespan. Here, we design a two-site bonding strategy aiming to reinforce the mechanical stability of the SnO2/perovskite interface and perovskite layer using a multifunctional organic salt, 4-(trifluoromethoxy)phenylhydrazine hydrochloride (TPH).
