Graphene oxide-iron oxide (GO-Fe3O4) nanocomposites were synthesised by co-precipitating iron salts onto GO sheets in basic solution. The results showed that formation of two distinct structures was dependent upon the loading. first structure corresponds to a low loading up 10 wt%, associated with beneficial intercalation within Fe3O4 nanoparticles and resulting higher surface area 409 m(2) g(-1). High beyond wt% led aggregation undesirable stacking sheets. presence strong interfacial...

Mg−Al−CO3 layered double hydroxide (LDH) was synthesized, and its thermal evolution investigated using X-ray diffraction, FTIR spectroscopy, thermogravimetric analysis (TGA). The resultant LDH derivatives showed excellent CO2 adsorption capabilities, especially suitable for high-temperature separation from flue gases. Calcination of crystalline LDHs at 400 °C led to phase transformation yielding amorphous Mg−Al mixed oxides having a sorption capacity 0.49 mmol/g 200 °C. Reversible...
A screening of potential calcium precursors for the production CaO sorbents CO2 capture at high temperature was conducted in this work. The studied include microsized carbonate (CC-CaO), hydroxide (CH-CaO), nanosized (<70 nm) (CC70 nm-CaO), (<160 oxide (CaO160 acetate hydrate (CA-CaO), l-lactate (CL-CaO), formate (CF-CaO), citrate tetrahydrate (CCi-CaO), and d-gluconate monohydrate (CG-CaO). capability these investigated using a thermogravimetric analyzer (TGA) multiple cycles. CG-CaO...
Sorbents for high temperature CO2 capture are under intensive development owing to their potential applications in advanced zero emission power, sorption-enhanced steam methane reforming hydrogen production and energy storage systems chemical heat pumps. One of the challenges is prevention sintering sorbent (normally a calcium oxide derivative) which causes capacity material deteriorate rapidly after few cycles utilization. Here we show that simple wet mixing method can produce...
Abstract A major challenge in silica membranes for gas separation is to maintain a robust pore structure the presence of steam. In this work, use carbonized template proposed reduce damage by inhibiting migration along membrane surface. This departs from conventional wisdom creating hydrophobic surfaces achieve hydrostability. The carbonized‐template molecular sieve (CTMSS) can then be applied clean‐energy systems such as hydrogen and carbon dioxide sequestration, reactors where steam present.
Coal is the most abundant fossil fuel in world and likely to outlast gas oil for centuries. However, with global issues like climate change at forefront of public attention there a trend towards development carbon constrained economy. As result, research has intensified last decade on modes operating coal fired power plants capture storage (CCS). In particular, pre-combustion options via gasification, especially integrated gasification combined cycle (IGCC) processes, are attracting...

Mg−Al−CO3 layered double hydroxide (LDH) was synthesized, and its thermal evolution investigated using X-ray diffraction FTIR techniques. These patterns revealed the phase transformation of crystalline LDH to a nearly amorphous oxide (LDO). LDOs derived after calcination at 400 °C showed good sorption potential for CO2, especially in context high-temperature CO2 separation from flue gases. Presence water feed proved have positive effect as increased 2.72% (0.61 mmol/g) 3.14% (0.71 tested...
This review provides a global overview of microporous silica based membranes for desalination via pervaporation with focus on membrane synthesis and processing, transport mechanisms current state the art performance. Most importantly, recent development novel concepts improving hydro-stability separating performance are critically examined. Research into has focussed three primary methods hydro-stability.
