Hydrogen Selection: A Fuel Suitable for environment as an opportunity for teaching green chemistry

Abstract

With emergence of green chemistry, some scientific principles, approaches and methods appeared. One of its advantages is human and environment health. Green chemistry is a dynamically social, economic, and scientific adjustment. Increasing consumption of fossil fuels and the shortage of these resources on one hand and seriousness of other problems derived from the increase of environmental pollutants have made politicians and programmers in energy sector mobilize their expertise in order to be able to carry out structural researches on how to change energy carriers. In comparison with other fuels, hydrogen, if mixed with oxygen without producing common pollutants, can become a kind of energy with high efficiency due to its high thermal value; hence, all other industries including automobile industry have commenced to conduct broad researches on how to use this energy. Using hydrogen with fuel cell depicts a bright future. In the long run, hydrogen, as the best choice and the most economic fuel, has high potential to be used in fuel cell automobiles. Iran’s development depends on the use of fuel cell technology. In near future, fuel cell will compete with ignition engines. Therefore, hydrogen production and saving solar energy using photo -catalytic decomposition can be considered as a suitable way to solve some of the problems that we addressed. Nowadays, many students are interested in preserving and surviving environment. They want to know how human activity and chemical industry affect our planet health. So, chemistry and its correct teaching provide a suitable opportunity to start discussing chemistry, environment and human health.
