Existing environmental conditions and global climate changes are constantly reminding us that we no longer can use fossil fuels because of its worst effects on climate patterns. So, there is an urgent need in order to find the alternatives of the fossil fuels. By doing this, it will become easier for us to lessen the damages created by the use of fossil fuels. The cleanest low carbon fuel is none other than hydrogen.
Hydrogen can react with oxygen to make the release of energy possible. But it will emit nothing more dangerous than water as a result or a product. It should be noticed that most of the hydrogen in already locked up & cannot be used. * How to charge moving vehicle through wireless.
Generating hydrogen:
Hydrogen can be generated by the splitting of H2O but the problem is that the energy used in this process is more than the produced hydrogen can return. Through solar power, the splitting of water was often carried out for solar to hydrogen conversion. There are some materials e.g. titanium oxide is used traditionally for the conversion of sunlight into chemical energy. Titanium oxide is also known to be semiconductors. These methods were not considered to be efficient because most of the sunlight is wasted, only UV part of the light is absorbed. * How to turn scrap material into batteries.
Modern method:
The team of a well-known university in Osaka has created a material through which a broader spectrum of sunlight can be harvested. This material helps not only in maximizing the absorbing light but also increases efficiency for the process of water splitting. For this purpose, the core is the semiconductor i.e. lanthanum titanium oxide. The surface of it is partly coated with tiny spots of gold which also known as to be nanoparticles. After that, the ultra-thin sheets of black phosphorus (serves as a light absorber) is mixed with the gold covered lanthanum titanium oxide. * Concept of self-driving cars.
Black phosphorus – an amazing material:
Undoubtedly, black phosphorus is an amazing material. We can amend the frequency of the light by changing its thickness from ultra thin to massiveness. Lanthanum titanium oxide can never be achieved with black phosphorus. Black phosphorus is motivated to release electrons after the removal of energy. Electrons are then conducted to the nanoparticles of the gold that is coated with lanthanum titanium oxide. Free electrons and gold nanoparticles are afterward transmitted into the semiconductor of LTO (lanthanum titanium oxide).
A better idea:
This material that is developed recently for the production of hydrogen fuel by the use of solar energy is considered to be as the best one. Because this is not done through the traditional method rather done through modern one that is more efficient. The production of hydrogen by this material has not only broader spectrum of light absorption but also the conduction of the electrons are more proficient. * Future of technology in Pakistan.
Moreover, this method is highly preferable because it is more pure and active than lanthanum titanium oxide. Therefore, we can say that useful harvesting of solar energy can be used for the production of clean hydrogen fuel. Furthermore, the environment can be cleaned in an easier and effective way. * Top ten engineering universities in Pakistan.
