This brief review article describes the structure, properties and applications of natural and
synthetic zeolites, with particular emphasis on zeolites obtained from natural or waste …

Over the years, the production of waste ash from many sources (eg coal, biomass, industrial,
animal, and municipal solid waste) and from conventional and renewable energy …

Synthesis of zeolite through hydrothermal process has been commonly used for decades.
However, it does not satisfy the serious terms of sustainability that leads to reduction of …

Geopolymers produced from an aluminosilicate precursor and an alkaline activating solution
have emerged as low carbon alternative binders which can substitute for Portland cement …

This study describes the use of alkaline silicate solutions produced by mixing silica fume
(SF) or rice husk ash (RHA) with aqueous NaOH, as alternative silica-based activators for …

The use of low-cost, renewable or waste resources to create engineered silica particles is a
valuable example of sustainability. Rice husks are renewable resources that can be used to …

The objective of the present work is to develop a green procedure for preparation of silica
powders from rice husk ash (RHA) via a carbonation route. The raw materials, RHA and …

The transesterification of soybean oil with methanol was carried out in the presence of Li-
modified rice husk ash catalyst at atmospheric pressure. The catalyst was prepared using a …

As a potential precursor, the utilization of sugarcane bagasse ash imparts enormous
technical and environmental benefits to human society. However, its rich crystal content …

The adsorption of the dyes Basic Red 46 (BR46) and Reactive Yellow 176 (RY176) from
aqueous solution onto natural and modified zeolites has been investigated. The surfactants …
