Dandanes so najbolj pogost način pridobivanja energije fosilna goriva in jedrske elektrarne. Uporaba fosilnih goriv predstavlja tako okoljevarstveni problem, kot tudi problem pomanjkanja le-teh. Ker je energija ena najbolj pomembnih potreb razvitega sveta in ker se zahteva po energiji iz leta v leto viša, moramo iskati nove in zelene vire energije. Večina alternativnih virov energije je odvisnih od vremena ali drugih naravnih pojavov, ki omejijo konstantno pridobivanje energije. Veliko raziskav pa je bilo narejenih tudi na področju pridobivanja energije s pomočjo vodika. Problem pa se pojavi pri shranjevanju, saj je vodik eksploziven in ga moramo hraniti kot plin pod tlakom ali kot tekočino. Tako amonijak kot tudi metanol predstavljata varen način shranjevanja vodika, ki ga lahko iz obeh spojin pridobimo z uporabo radiolize. Radiolizo pa lahko uporabimo tudi za pretvorbo CO2, ki je eden izmed najbolj pogostih toplogrednih plinov. Iz rezultatov analiz je razvidno, da je med vsemi katalizatorji najbolje deloval katalizator TiO2.

• Title: Catalyst efficiency comparison at radiolysis of ammonia, methanol and carbon dioxide

Abstract

Most energy today is produced by fossil fuels and nuclear power plants. Use of fossil fuels is not only a threat to the environment but they are also limited. Because energy is nowadays one of the most important human needs and because its need is growing yearly, we need to look for new and green energy sources. Most of alternative energy sources are highly dependent on weather and other natural occurrences that limit the constant energy production. There has been a lot of research in the field of energy production via hydrogen. But the problem with it is the storage due to hydrogens explosive nature and it needs to be kept as a compressed gas or as a liquid. Not only ammonia but also methanol is a safe way to store hydrogen that can be accessed with radiolysis. Radiolysis can also be used for conversion of CO2 which is number one greenhouse gas today. During our research we discovered that the best results can be achieved with TiO2 catalyst.
