ABSTRACT
At present, carbon dioxide (CO2) is the largest contributor among greenhouse gases. This article addresses the potential application of photo catalysis to the reduction of CO2 emissions from industrial flue gas streams. Not only does this process remove CO2, but it can also convert CO2 into other chemical commodities such as methane, methanol, and ethanol. In addition, the photo catalytic process can consume less energy than conventional methods by harnessing solar energy. Given these advantages, photo cataly ....etc

New Way to Convert CO2 into Methanol.
We are familiar with the side effects of fossil fuels and its impact on environment. Right now the fossil fuels seem to be necessary evil we canâ„¢t do without. Scientists want alternative fuels that have none of the ill effects of traditional fuels
a combination of silica and hydrogen known as hydrosilane. Hydrosilane is added to the NHC-activated carbon dioxide, which is converted into methanol through hydrolysis. Dr Yugen Zhang who is the IBN team leader and principal research scientist elaborates ....etc

Catalytic degradation of waste plastic into fuel range hydrocarbons


Introduction
The huge amount of plastic waste that resulted
from the dramatic increase in polymer production
gives rise to serious environmental concerns, as
plastic does not degrade and remains in the
municipal refuse tips for decade . According to
a nation wide survey conducted in the year 2003,
more than 10,000 MT of plastic waste is
generated daily in our country, and only 40 wt ....etc

ABSTRACT
Necessity is the mother of invention. Energy crisis is the cry of
future.
The historical and the present-day civilization are closely interwoven
with energy and in future, our existence will be more dependent upon
energy. The conventional sources of energy, the single most important
pre-requisite for power generation, are depleting fast. The world is
heading towards a global energy crisis mostly due to running out of
these energy sources; decreasing the dependency on fossil fuels is
recommen ....etc
