Physisorption of nitrogen and oxygen by MCM-41, a model mesoporous adsorbent

Abstract: Physisorption measurements of nitrogen and oxygen reveal that MCM-41 has a well defined mesoporous structure and is a highly promising model adsorbent.

“…Grandes áre-as de superfície específica (de até 1500 m 2 .g -1 ) têm sido obtidas. Devido a esta estrutura regular de poros e estreita distribuição de tamanho, o MCM-41 é usado em várias aplicações, principalmente, em cromatografia 122,123 , catálise 124 e, mais recentemente, como matriz template na síntese de polímeros condutores e outros materiais 125 . 130 .…”
