TL;DR: The potential of polymer-derived-ceramics can only be fully achieved if the type of fabrication method used is tailored taking into account the specific application of interest as discussed by the authors, and a vast amount of research has been conducted, in the past decade, towards the fabrication and characterization of porous ceramics produced from different polymeric precursors, such as polysiloxane, polycarbosilane and borazine.

TL;DR: The heating applied from the bottom of molds promoted the nucleation, expansion and rising of gas bubbles, and the creation of a ceramic matrix with axially oriented channels interconnected by small round pores, enabling these lotus-type ceramics to be advantageously used as catalytic supports and adsorbents in several environmental control applications.

TL;DR: In this paper, mesoporous silicon oxycarbide (SiOC) components were formed with the use of "molecular spacer" (a sacrificial vinyl-terminated linear siloxane which while decomposing during pyrolysis generates pores with size proportional to the molecular weight), followed by a post-pyrolyisation etching treatment by hydrofluoric acid (HF) to obtain C-rich SiOC samples having additional micro-/mesoporosity and specific surface area reaching to 774m2/g.

TL;DR: TUBITAK et al. as mentioned in this paper used preceramic polymer mixture and a catalyst to produce carbonaceous SiOC (C-rich SiOC, sample W-HF), which was tested as an adsorbent material to remove both heavy metal ions (Cr (III), Pb (III, and Cd (II)) and cationic dyes (Methylene Blue (MB), Rhodamine B (RB), and Crystal Violet (CV)) from aqueous solutions.

TL;DR: There are a good many advantages of the proposed method, but using an environmentally friendly reagent free system, no organic solvent employment and its quick nature, and being a sensitive and reliable method are the most obvious ones.
