## Abstract The hydroxylation of benzene to phenol with hydrogen peroxide was investigated using different solvents and a series of catalysts, obtained by modification of titanium silicalite (TSβ1). The best results were obtained after postβsynthesis treatment of TSβ1 with NH~4~HF~2~ and H~2~O~2~.
Four types of carbon fiber microelctrodes modified with polyaniline (PAn) and platinum particles (Pt) were fabricated to determine H 2 O 2 at ΓΎ 0.60 V (vs. SCE). The sensitivity, stability and selectivity of different electrodes were compared. The electrode modified with a sandwich film of PAn-Pt-PA
