Annotation	Synthetic diamond films are routinely grown using chemical vapor deposition (CVD) techniques. This study reviews the fabrication of various porous diamond-based structures using linear antenna microwave plasma (LAMWP) CVD, a low-cost technology for growing diamond films over a large area at low pressure and at low temperature. From a technological point of view, 2 different approaches, i.e., templated diamond growth using 3 different prestructured porous substrates and direct bottom-up growth of ultra-nanoporous diamond films, are successfully employed to form diamond-based structures with controlled porosity and an enhanced surface area. As a bottom-up strategy, the LAMWP CVD system allows diamond growth at as high as 80% CO2 in the CH4/CO2/H2 gas mixture. In summary, the low-pressure and cold plasma conditions in the LAMWP system facilitate the growth on 3D prestructured substrates of various materials that naturally form porous self-standing diamond structures.
