Summary: The Si/Al ratio of 50 in HZSM-5 zeolites was found to have the highest specific surface area and porosity, while decreasing the Si/Al ratio resulted in higher enthalpy of Bronsted sites and increased acidity strength. This shift also led to changes in the length of the O-H moiety or the acidity strength of Bronsted sites, as indicated by NH3-TPD profiles.

Summary: This study investigates the decomposition mechanism of the key cellulose pyrolysis intermediate, levoglucosan, in biomass catalytic fast pyrolysis. Experimental results show that furan and furfural are key intermediates in the formation of aromatic hydrocarbons. Theoretical modelling reveals a direct pathway from levoglucosan to furan without furfural as an intermediate.

Summary: This study investigates the differences between in situ and ex situ catalytic fast pyrolysis methods for biomass treatment. It finds that both methods can improve the quality of bio-oil but decrease the yield. In situ CFP process prevents the transfer of heteroatoms to bio-oil while ex situ CFP process promotes the transfer. Additionally, ex situ CFP reaction significantly increases the content of aromatic hydrocarbons.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

Summary: This study systematically investigates the key roles of Nafion on Cu nanoparticles electrocatalyst for CO2RR. The Nafion modifier suppresses the hydrogen evolution reaction, increases CO2 concentration and mass transfer process, and activates CO2 molecule to enhance C2 product generation. As a result, the selectivity of the hydrogen evolution reaction is reduced and the efficiency of C2 products is significantly improved.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
