Catalytic performances of CeO2@SBA-15 as nanostructured material for biodiesel production from Podocarpus falcatus oil

Evaluation of two core–shell (Ag2S@- and Bi2S3@-) sensors based on a metal–organic framework (NH2-MIL-125-Ti)/polyaniline for the electroanalysis of uric acid in urine samples

“…4(A) exhibited type I isotherms recorded at 77 K with no hysteresis, indicating a significant presence of both micropores and mesopores within the framework structure of the MOF. 35–44,53–55 The BET surface area of (a) was 1085.27 m 2 g −1 which is comparable to the value reported 35 (1169 m 2 g −1 ). Moreover, this surface area decreases drastically to 415.82 m 2 g −1 and 372.52 m 2 g −1 after surface modification with Ag 2 S and Bi 3 S 2 , respectively, and can be justified by the partial occupation of the micropores, mesopores and obstructed pores of the pristine MOF as shown in Fig.…”
