The amount of waste heat generated annually in the UK exceeds the total annual electricity demand. Hence, it is crucial to effectively harness all available sources of waste heat based on their varying temperatures. Through suitable technologies, a s

Hydrogen is attractive as a clean fuel for motor vehicles and porous carbons represent promising hydrogen storage materials. Here, Mokaya and colleagues incorporate oxygen-rich functional groups into porous carbons with high microporosity, showing th

Carbonisation of potassium phthalimide (PPI) generates microporous carbons with exceptional gas uptake at 25 °C; 5.2 mmol per g CO2 @ 1 bar, and methane storage of 338 cm3 (STP) cm−3 at 100 bar with 100–5 bar working capacity of 249 cm3 (STP) cm

Tropical volcanic ash is a cheap and sustainable source of high purity silica for the synthesis of zeolites; the zeolite type, whether Na–X, Na–P or hydroxysodalite, depends on the amount of SiO2 and Na2O in the synthesis hydrogels.

Activated carbon cloth (ACC) has the potential to be extremely useful in gas capture and storage applications as it combines high porosity, robustness, and flexibility with ease of handling. While it has been produced by a few researchers, the synthe

In this study biochars and activated carbons were synthesized either directly via the pyrolysis of sodium carboxymethyl cellulose (NC) or via hydrothermal carbonization of sawdust (SD) in an aqueous solution of KOH. The amount of porogen was varied b
