Enhanced Photocatalytic Performance toward CO2 Hydrogenation over Nanosized TiO2-Loaded Pd under UV Irradiation
A series of Pd/TiO2 photocatalysts were synthesized by a simple glucose reduction method, and their photocatalysis properties were evaluated in an array of CO2 hydrogenations. The samples were characterized by XRD, SEM, TEM, EDX, EDX mapping, UV-vis DRS, Raman spectroscopy, PL spectroscopy, XPS, and N-2 adsorption. In terms of product yields (in micromoles per gram of Catalyst), a 1.0 wt % Pd/Ti...

Preparation, characterization and enhanced performance of functional crosslinked membranes using poly(vinyl alcohol) as macromolecular crosslinker for fuel cells
Functional cross-linked membranes based on sulfonated poly(arylene ether ketone sulfone) containing pendant carboxyl groups (C-SPAEKS) and poly(vinyl alcohol) (PVA) as macromolecular crosslinker were fabricated. The covalent cross-linking reaction was realized by thermal treatment between carboxyl and hydroxyl groups. The cross-linked membranes exhibited favorable thermal stability, good mechanica...

66. Covalent Bonding of Sulfur Nanoparticles to Unzipped Multiwalled Carbon Nanotubes for High-Performance Lithium–Sulfur Batteries
The use of sulfur as a cathode material for lithium-sulfur (Li-S) batteries has attracted significant attention due to its high theoretical specific capacity (1675 mA h g(-1)); however, practicality is hindered by a number of obstacles, including the shuttling effect of polysulfides and the low electrical conductivity of sulfur. Herein, ball milling sulfur with unzipped multiwalled carbon nanotube...

62. Tuning the morphologies of fluorine-doped tin oxides in the three-dimensional architecture of graphene for high-performance lithium-ion batteries
The morphology of electrode materials plays an important role in determining the performance of lithium-ion batteries (LIBs). However, studies on determining the most favorable morphology for high-performance LIBs have rarely been reported. In this study, a series of F-doped SnOx (F-SnO2 and F-SnO) materials with various morphologies was synthesized using ethylenediamine as a structure-directing a...

52. Three-dimensional Porous Carbon Composites Containing High Sulphur Nanoparticle Content for High-performance Lithium–Sulphur Batteries
Sulfur is a promising cathode material for lithium-sulfur batteries because of its high theoretical capacity (1,675 mA h g(-1)); however, its low electrical conductivity and the instability of sulfur-based electrodes limit its practical application. Here we report a facile in situ method for preparing three-dimensional porous graphitic carbon composites containing sulfur nanoparticles (3D S@PGC). ...

Free-standing, welded mesoporous carbon nanofibers as anode for high-rate performance Li-ion batteries
A novel type of renewable lignin-based mesoporous carbonized nanofibers (MCNFs) has been fabricated via electrospinning technique and thermal treatment, using lignin with polyacrylonitrile (PAN) as the carbon source and triblock copolymer Pluronic P 123 as the template. The obtained MCNFs were directly used as anodes of lithium-ion batteries (LIBs) without binder and current collector. The MCNFs a...

Facile hydrothermal treatment route of reed straw-derived hard carbon for high performance sodium ion battery
Although hard carbon is deemed to be the most potential industrialized sodium-ion batteries anode material, there are still some problems need to be solved. In this study, a waste biomass of reed straw is pretreated by using a new strategy-hydrothermal treatment instead of pickling and successfully transformed to hard carbon materials through subsequent carbonization process. The reed straw carbon...
