FOTÓLISE DE GELO DE ÁGUA POR RAIOS-X MOLES E A PRODUÇÃO DE H2O2 DURANTE AS FASES DE IRRADIAÇÃO E AQUECIMENTO

Resumo
Gelos astrofísicos ricos em H2O (água) estão sempre expostos a radiações ionizantes no espaço, assim como a eventuais mudanças de temperatura. Seus estudos em laboratório permitem compreender seus comportamentos e mudanças químicas, além de permitir a quantificação de parâmetros físico-químicos importantes do próprio gelo. No presente trabalho, uma amostra de gelo de água a 12 K foi irradiada por raios-X moles na linha de luz SGM do LNLS/CNPEM até atingir o equilíbrio químico, e em seguida, foi aquecida até 220 K. Utilizando espectroscopia infravermelha (IR), mapeamos a evolução química da amostra e quantificamos a produção do seu principal produto, a molécula de H2O2. O estudo tem implicações na química das regiões de formação estelar, bem como em regiões frias do sistema solar.
