Silver Nanoparticles Confined in SBA-15 Mesoporous Silica and the Application as a Sensor for Detecting Hydrogen Peroxide

Table 1

Physicochemical properties of the samples. S_BET, BET specific surface area; 𝑉_𝑡, total pore volume; D_BJH, pore diameter calculated using BJH method; d₁₀₀, periodicity of host SBA-15 derived from XRD. The wall thicknesses, t, was calculated as A₀-pore size (A₀ = 2d(100)/√3).
