TITLE: Understanding the size limits of silica pore formation by in situ grazing incidence small angle X-ray scattering

The data consists of small angle scattering data (raw and processed) recorded at Diamond Light Source I07. Processed data includes a number of 1D projections (horizontal, radial) of the data as well as the peaks followed in the horizontal scattering profiles. 

Experiment no: si20593-1

A Dectris Pilatus 2M was used to record the raw data in 100 ms intervals followed by 20 ms readout time.Each measurement run consisted of 700 frames, leading to 700x0.12 s=84 s.

electrochemistry was driven by the application of -2 V vs Ag/AgCl for the duration of 60 s. Electrochemistry and scattering data aquisition were started simultaneously for each measurement. 

TEOS: tetraethyl orthosilicate

CTAB: hexadecyltrimethylammonium bromide 

OTAB: octadecyltrimethylammonium bromide

Basic solution composition: 

20 ml of 0.1 M NaNO3 in H2O added to 20 ml of EtOH; adjusted to pH=3 using 0.2 M HCl; +480 mg of CTAB/OTAB; + 905 uL of TEOS;+ X amount of mesitylene (as described below).

The raw data for 8 measurement runs are included as follows:


Sample2A1: CTAB, no mesitylene

Sample1A2: CTAB, [mesitylene]/[CTAB]=0.1

Sample2A3: CTAB, [mesitylene]/[CTAB]=0.5

Sample1A4: CTAB, [mesitylene]/[CTAB]=1.0

Sample1B1: OTAB, no mesitylene

Sample1B2: OTAB, [mesitylene]/[OTAB]=0.5

Sample1B3: OTAB, [mesitylene]/[OTAB]=1.0

Sample1B4: OTAB, [mesitylene]/[OTAB]=2.0


Corresponding chronoamperometry data can be found in the folder "I07silicaEC".
